Anionic 1-Aza-3,4-diphospholides as redox active ligands

Herein we present the redox active behaviour of the sodium salt of 1-aza-3,4-diphospholide Na[1]. Cyclic voltammetry in MeCN shows an irreversible reduction and an irreversible oxidation wave indicating EC mechanisms. This anionic heterocycle is chemically oxidized with hexachloroethane likely to a short-lived 1-aza-3,4-diphospholyl radical which rapidly dimerizes to give bis(1-aza-3,4-diphospholyl) (2) which contains a tetraphosphane unit, PPPP. In solution and in the solid state a rac- and meso-isomer have been identified. The oxidation reaction is chemically reversible, and using lithium metal, the central PP bond in 2 can be cleaved to afford Li[1]. Both the anion [1]− and the PP coupled dimer 2 have been applied as ligands in combination with iron carbonyl precursors to isolate the strawberry red complex [FeCp(η1-1)(CO)2] (3). This complex undergoes dimerization under the loss of carbon monoxide to form the complex [Fe2(​Cp)2(μ2-1)(CO)2] (4-syn and 4-anti). The reaction of bis(1-aza-3,4-diphospholyl) 2 with [Fe3(CO)12] in THF leads to cleavage of the PP bond, and a dinuclear complex [Fe2(μ2–1)2(CO)6] (5) with a direct Fe(I)Fe(I) bond [Å = 2.5866(4)] is obtained.

Synthesis, Characterization and Antioxidant Activity of Two Novel Oxovanadium (IV) Curcuminoids

The reaction of bis[4-hydroxy-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (curcumin) and two novel ligands of bis[4- tetrabenzylglucose-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (bis(tetrabenzylglucose)curcumin) (BTBGC) and bis[4-tetraacetylglucose- 3-methoxyphenyl]-1,6-heptadiene-3,5-dione (bis(tetraacetylglucose)curcumin) (BTAGC) with vanadium in methanol, in a 2:1 molar ratio, which yield the complexes of ML2 where M is [VO]2+, have been synthesized and characterized by FT-IR, mass spectrometry, 1H NMR spectroscopy and elemental analysis. These novel compounds were also examined for their antioxidant activity (using Trolox Equivalent Antioxidant Capacity (TEAC) antioxidant assay as a measure of their overall ability to scavenge free radicals compared to antioxidant standards such as Trolox); compounds with free hydroxyl groups were more active than those one whose locking such and also the metal complexes showed more activity than Trolox. The antioxidant capacity was decreased in BTBGC, BTAGC and their complexes compared to curcumin and its oxovanadium (IV) complex, corroborating the importance of curcumin’s free phenolic OH groups for scavenging oxidants potential. Also, the presence of the methoxy group increases the activity.

A stable ring-expanded NHC-supported copper boryl and its reactivity towards heterocumulenes.

Reaction of bis(pinacolato)diboron with (6-Dipp)CuOtBu generates a ring-expanded N-heterocyclic carbene supported copper(I) boryl, (6-Dipp)CuBpin. This compound showed remarkable stability and was characterised by NMR spectroscopy and X-ray crystallography. (6-Dipp)CuBpin readily dechalcogenated a range of heterocumulenes such as CO2, isocyanates and isothiocyanates to yield (6-Dipp)CuXBpin (X = O, S). In the case of CO2 catalytic reduction to CO is viable in the presence of excess bis(pinacolato)diboron. In contrast, in the case of iso(thio)cyanates, the isocyanide byproduct of dechalcogenation reacted with (6-Dipp)CuBpin to generate a copper(I) borylimidinate, (6-Dipp)CuC(NR)Bpin, which went on to react with heterocumulenes. This off-cycle reactivity gives selective access to a range of novel boron-containing heterocycles bonded to copper, but precludes catalytic reactivity.

Development of structurally extended benzosiloxaboroles - synthesis and in vitro biological evaluation.

The synthesis of potassium 6-hydroxy-7-chloro-1,1-dimethyl-3,3-difluorobenzo-1,2,3-siloxaborolate 5b from readily available 4-bromo-2-chlorophenol was developed. This compound proved useful in various derivatizations resulting in a wide range of O-functionalized benzosiloxaboroles. Reactions of 5b with selected substituted benzoyl chlorides gave rise to a series of respective derivatives with 6-benzoate side groups attached to the benzosiloxaborole core. Furthermore, treatment of 5b with substituted benzenesufonyl chlorides afforded several benzosiloxaboroles bearing functionalized benzenesulfonate moieties at the 6 position. The synthesis of related chloropyridine-2-yloxy substituted benzosiloxaboroles was accomplished by a standard approach involving silylation/boronation of appropriate heterodiaryl ethers. Investigation of biological activity of obtained compounds revealed that some benzoate and most benzenesulfonate derivatives exhibit high activity against Gram-positive cocci such as methicillin-sensitive Staphylococcus aureus ATCC 6538P as well as methicillin-resistant S. aureus ATCC 43300 with the MIC values in the range of 0.39–3.12 mg L−1. Some benzenesulfonate derivatives showed also potent activity against Enterococcus faecalis ATCC 29212 and E. faecium ATCC 6057 with MIC = 6.25 mg L−1. Importantly, for the most promising cocci-active benzenesulfonate derivatives the obtained MIC values were far below the cytotoxicity limit determined with respect to human normal lung fibroblasts (MRC-5). For those derivatives, the obtained IC50 values were higher than 12.3 mg L−1. The results of antimicrobial activity and cytotoxicity indicate that the tested compounds can be considered as potential antibacterial agents.

One-pot synthesis of cobalt complexes with 2,6-bis(arylimino)phenoxyl/phenthioxyl ligands and catalysis on isoprene polymerization.

Several cobalt complexes supported by 2,6-bis(arylimino)phenoxyl/phenthioxyl ligands κ2N,X-Ar[NXN]CoCl(THF) (1a, X = O, Ar = 2,6-Me2C6H3; 1b, X = O, Ar = 2,6-iPr2C6H3; 2a, X = S, Ar = 2,6-Me2C6H3; 2b, X = S, Ar = 2,6-iPr2C6H3) were synthesized by direct oxygen(sulfur) insertion into the C-Co bond of the mixed-valence cobalt complexes {κ2C,N,η6-Ar[NCN]Co-κN-CoCl(μ-Cl)}2. Crystallization of 1b in the presence of water gave the hydrolysis product 1b'. Treatment of Ar[NCN]Li with dioxygen followed by the addition of CoCl2 afforded the heteroatomic complexes {κ2N,O-Ar[NON]Co(μ-Cl)2Li}2 (3a, Ar = 2,6-Me2C6H3; 3b, Ar = 2,6-iPr2C6H3) or κ2N,O-Ar[NON]Co2Cl2(μ-Cl)2Li(THF)2 (4a, Ar = 2,6-Me2C6H3; 4b, Ar = 2,6-iPr2C6H3) depending on the amount of CoCl2 used. The Co(iii)/Li heterometallic complex 3b' with imino-phenoxyl-amino ligands was formed probably via a redox reaction of 3b. The reactions of Ar[NCN]Li with elemental sulfur and CoCl2 gave κ2N,S-Ar[NSN]Co2Cl2(μ-Cl)2Li(THF)2 (5a, Ar = 2,6-Me2C6H3; 5b, Ar = 2,6-iPr2C6H3) respectively. These complexes were well characterized by FT-IR and elemental analyses, and the molecular structures of 1b', 3b', 4a, and 4b were confirmed by X-ray crystallography. Upon activation with Al2Et3Cl3 in toluene, these complexes showed high activities in isoprene polymerization affording cis-1,4 enriched polymers with a moderate molecular weight (0.85-4.72 × 104 Da).

Сравнение коллективного ускорения протонов и дейтронов в диоде Люса с полиэтиленовым анодом

Collective acceleration of protons and deuterons is compared in the same geometry of a Luce diode with a polyethylene anode at an accelerating diode voltage of 250 kV, current and pulse duration of relativistic electrons up to 30 kA and 90 ns, respectively. The accelerated ions were intercepted by B4C, BN, and AlN plates, in which analytical radionuclides were produced according to nuclear reactions 10B( p , α)7Be, 12C( p, γ)13N, 10B( d , n )11C, 12C( d , n )13N, 14N( d , n )15O and 27Al( d , p )28Al. The ion energy was determined according to the ratios of activity of the analytical radionuclides, while the number of accelerated ions was calculated from the number of induced nuclei of the radionuclides. It was found that the velocities of the main group of protons and deuterons were the same within the measurement error, and the average number of ions accelerated in one pulse was, on average, 3 times higher when protons were accelerated.

Synthesis and characterization of polymeric and monomeric zinc phosphinates

Abstract The synthesis and characterization of polymeric and monomeric Zinc phosphinates are reported. Bis(hydroxymethyl)phosphinic acid is used as a ligand for the synthesis of both polymeric and monomeric phosphinates. A polymeric zinc phosphinate is synthesized by the reaction of bis(hydroxymethyl)phosphinic acid with zinc acetate dihydrate at room temperature. Each phosphinate ligand coordinates with two different zinc centers to generate polymeric zinc phosphinate. The above reaction is carried out with the addition of 1,10-phenanthroline to form monomeric zinc phosphinate compound. When the N-donor chelating ligand (1,10-phenanthroline) is introduced, the construction of polymeric zinc phosphinate is blocked by 1,10-phenanthroline which facilitates the formation of discrete monomeric zinc phosphinate. The synthesized zinc phosphinate compounds are characterized by FT-IR, 1H, 13C and 31P NMR, and also noticed thermal stability by thermogravimetric analysis (TGA). Both the polymeric and monomeric zinc phosphinate compounds are subjected for calcinations at 800 °C to produce zinc metaphosphate materials. Finally the crystalline phase of zinc metaphosphate materials is characterized by powder x-ray diffraction technique (PXRD).

A Facile synthesis of some novel 1,3,4-thiadiazoles and pyridines linked to benzofuran as antimicrobial agents.

In the present study, a new series of benzofuran-integrated 1,3,4-thiadiazoles were prepared starting from pyrazol-4-carboxaldehyde derivatives 3a,b. Thus, reaction of compound 3a,b with benzyl hydrazine carbodithioate afforded hydrazine carbodithioate derivatives 4a,b. Treatment of compound 4a with hydrazonoyl halides 5e,f afforded 1,3,4-thiadiazoles 6a, b while the reaction of 4b with hydrazonoyl halides 5a-d yielded 1,3,4-thiadiazoles 7a,b. on the other hand, new pyridine derivatives can be synthesized via the reaction from the reaction of chalcone 8 with different C-nucleophile such as ethyl acetoacetate, benzoyl acetonitrile or acetyl acetone. All the new derivatives were characterized by spectral data. Some of the newly prepared compounds were investigated against different pathogenic microbes. The results of the antimicrobial activity revealed that all the tested compounds showed no activity except compound 6a which showed weak activity against all tested microorganisms. Compound 6b was weak active against B. subtilis and compound 7c was intermediate active against E. coli.

Measurements of neutron energy spectra of 9Be(d,n)10B reaction with a thick beryllium target * *Supported by the National Natural Science Foundation of China (11875155, 11705071, 12075105), the NSFC-Nuclear Technology Innovation Joint Fund (U1867213), the NSAF (U1830102), the Fundamental Research Funds for the Central Universities of China (lzujbky-2020-kb09) and the Project of National Defense Science and Technology Industry for Nuclear Power

Novel measurements of the neutron energy spectra of the 9Be(d,n)10B reaction with a thick beryllium target are performed using a fast neutron time-of-flight (TOF) spectrometer for the neutron emission angles and , and the incident deuteron energies are 250 and 300 keV, respectively. The neutron contributions from the 9Be(d,n)10B reaction are distributed relatively independently for the ground state and the first, second, and third excited states of 10B. The branching ratios of the 9Be(d,n)10B reaction for the different excited states of 10B are obtained for the neutron emission angles and , and the incident deuteron energies are 250 and 300 keV, respectively. The branching ratio of the 9Be(d,n)10B reaction for the third excited state decreases with increase in the incident deuteron energy, and the branching ratios for the ground state and the second excited state increase with increase in the neutron emission angle.

Isospin triplet A=12: search for states with enhanced radii

Two independent methods: Asymptotic Normalization Coefficients (ANC) and Modified Diffraction Model (MDM) were applied to new and existing experimental data to search for states with enhanced radii in isobaric analogue states (IAS) of 12B and 12N. The ANC analysis of the 11B(d,p)12B reaction at Ed = 21.5 MeV has confirmed neutron halo existence for two states of 12B: 2−, 1.67 MeV and 1−, 2.62 MeV [1]. Some new results were obtained for higher excited states: halo-like states were observed for 0+, 2.72 MeV and 3−, 3.39 MeV states. It should be mentioned that the last one is unbound state, which is 19 keV above the neutron emission threshold and in both states last neutron has a non-zero orbital momentum (ln=1 and ln=2 correspondingly). We propose to use MDM to study isobaric analogue states of 12B in the mirror 12N nucleus and apply it to analyze the (3He,t) reaction data. The existing in the literature data are not completed enough to make definite conclusion about halo in the 2− and 1− states of 12N. This fact simulated us to carry out a new experiment on the 12C(3He,t)12N reaction at the end of 2018. The measurements were conducted at the University of Jyväskylä (Finland) using the K130 cyclotron to produce a 3He beam at E(3He)=40 MeV. The differential cross sections of the 12C(3He,t)12N reaction were measured in the c.m. angular range 8°–70°. Preliminary results for angular distributions are obtained. MDM analysis of preliminary (3He,t) experimental data is done.

Helium-3 as a Perspective Fuel for Power Generation through Aneutronic Thermonuclear Fusion

The aneutronic D3–He (deuterium–helium-3) fuel cycle is considered as a viable alternative to D–T (deuterium–tritium) fusion since it is ecologically much safer than the latter. It is practically as safe as the aneutronic p–11B (proton–boron-11) reaction. The interest to aneutronic fuel cycles as perspective sources of thermonuclear energy is largely shown by privately-financed venture companies. The plasma-confinement techniques to be employed in planned D–3He thermonuclear reactors and their parameters are reviewed. The problem of helium-3 mining is discussed, and its terrestrial abundance is estimated. Possible applications of weakly-radioactive and aneutronic reactions and fuel cycles are considered.

Formations of aryl or pyrrole ring via palladium‐catalyzed CH functionalization on amido‐substituted quinones in the presence of amines or phosphines

AbstractA di‐substituted quinone (5), having two amido‐groups at opposite positions, was reacted with tertiary, secondary, or primary amines via a one‐pot reaction in the presence of palladium salt. Crystal structures of some of the products, 7b‐7c, from these reactions reveal that two new pyrrole rings are formed and linked to quinone framework of 5 by taking advantage of the in situ generated alkenyl moiety, which is from the reaction of amine with palladium salt. Furthermore, the reaction of di‐amido substituted diquinone (8a) with tertiary amines led to the formations of 9a‐9d with new pyrrole and benzene rings to the moiety of 8a. Similar procedures for the reaction of 8b with tertiary amines provides an alternated route to make notable 1,4,5,8‐phenanthrenetetraone derivatives, 9e and 9f. Moreover, the reaction of diquinone (8a) with tricyclohexylphosphine led to two products, 11 and 13, with new formation of furan ring as well as PC bond. Further reaction of 11 with NBu3 yielded 14 with newly formed pyrrole ring. Crystal structures of these newly‐formed compounds revealed by single‐crystal X‐ray diffraction methods substantiate the claim.

Synthesis and Antimicrobial Activities of Some New Bis(Schiff Bases) and Their Triazole-Based Lariat Macrocycles

New series of bis(amino-1,2,4-triazoles ‏) 5a–f were prepared by the reaction of bis(chloro) diamides 3a–d with 5-substituted-4-amino-1,2,4-triazoles-3-thiole (4a–c). Reaction of bis(amino) triazoles 5a–d with the appropriate aldehydes afforded the corresponding Schiff bases 7a–d in good yields. Similarly, cyclocondansation of bis(amino) triazoles 5a–d with 1,3-bis(2-formyphenoxy)-2-propanol furnished the desired lariat macrocycles 12a–d. The antimicrobial activities of the prepared bis(amines) 5a–c, e–g, Schiff bases 7a–d, 11a–b and lariat macrocycles 12a,c,d were evaluated against series of selected microorganisms. Some of the prepared derivatives showed good antimicrobial activity against gram positive bacteria and gram negative bacteria. The MIC values for some of the tested compound were investigated.

Nuclear reactions for protontherapy intensification

This paper presents some experimental results about the 7Li, 11B and 19F (p, α) nuclear reactions developed using proton beams at energy below 3 MeV in order to be applied to protontherapy. The energy released by proton beams during radiotherapy acts mainly at the end of the proton path in the biological medium, where it increases at high density inside the tumor. At this depth, it is possible to inject in the tumor compounds containing Li, B and F to generate energetic alpha particles from nuclear reactions. At the proton Bragg peak position it is possible to produce 1–8 MeV alpha particles, which enhance the energy density deposited in the tumor increasing the probability to damage the cells. Thanks to the higher relative biological efficiency of the alpha particles with respect to protons, it is expected that the alpha synergic particles defeat the tumor at lower doses.

Synthesis, antimicrobial studies, and molecular docking of some new dihydro-1,3,4-thiadiazole and pyrazole derivatives derived from dithiocarbazates

A series of 3-acetyl-2-aryl-5-methylthio-2,3-dihydro-1,3,4-thiadiazoles 3a–g, N- (4-acetyl-5-aryl-4,5-dihydro-1,3,4-thiadiazol-2-yl) acetamide derivatives 5a–e and spiro-compound 7 was prepared from starting material dithiocarbazates using N-methylpyrrolidone (NMP) /acetic anhydride mixture. Furthermore, a new series of 5-amino-3- (methylthio) -1-substituted-1H-pyrazole-4-carbonitrile derivatives 12a–d was prepared using two synthetic routes: (i) via reaction of bis (methylthio) methylene malononitrile 8 with carbothiohydrazides 11a–d, or (ii) via reaction of methyl 5-amino-4-cyano-3- (methylthio) -1H-pyrazole-1-carbodithioate 9a with primary/secondary amines. The antimicrobial screening of newly synthesized compounds revealed that compounds 3b, 7, and 12d are the most potent against the Gram-positive (S. aureus) and the Gram-negative (E. coli) bacteria compared to ciprofloxacin as reference drug. Mechanistically, the theoretical docking results of 3b, 7 and 12d suggested that they may act as potent inhibitors of theDNA gyrase.

Bis(aldehydes): Versatile precursors for novel bis(14H‐dibenzo[a,j]xanthenes), bis(pyrano[3,2‐c:5,6‐c']dichromenedione), and bis(dihydrobenzo[a]xanthenones) via multicomponent reactions

AbstractA synthesis of novel bis(4‐(14H‐dibenzo[a,j]xanthenes) and bis(dihydro‐8H‐benzo[a]xanthenones) was performed in good yields via pseudo‐multicomponent, or multicomponent reactions, of bis‐aldehydes with four equivalents of β‐naphthol or with a mixture of two equivalents of each β‐naphthol and dimedone in the presence of a catalytic amount of p‐toluenesulfonic acid. Bis(pyrano[3,2‐c:5,6‐c′]dichromenediones) or tetrakis(4‐hydroxy‐2H‐chromen‐2‐ones) could also be obtained in good yields through pseudo‐multicomponent reactions of bis(aldehydes) with four molar ratio of 4‐hydroxycoumarin.

Low-Valence Anionic α-Diimine Iron Complexes: Synthesis, Characterization, and Catalytic Hydroboration Studies.

The synthesis of rare anionic heteroleptic and homoleptic α-diimine iron complexes is described. Heteroleptic BIAN (bis(aryl)iminoacenaphthene) complexes 1-[K([18]c-6)(thf)0.5] and 2-[K([18]c-6)(thf)2] were synthesized by reduction of the [(BIAN)FeBr2] precursor complex using stoichiometric amounts of potassium graphite in the presence of the corresponding olefin. The electronic structure of these paramagnetic species was investigated by numerous spectroscopic analyses (NMR, EPR, 57Fe Mössbauer, UV-vis), magnetic measurements (Evans NMR method, SQUID), and theoretical techniques (DFT, CASSCF). Whereas anion 1 is a low-spin complex, anion 2 consists of an intermediate-spin Fe(III) center. Both complexes are efficient precatalysts for the hydroboration of carbonyl compounds under mild reaction conditions. The reaction of bis(anthracene) ferrate(1-) gave the homoleptic BIAN complex 3-[K([18]c-6)(thf)], which is less catalytically active. The electronic structure was elucidated with the same techniques as described for complexes 1-[K([18]c-6)(thf)0.5] and 2-[K([18]c-6)(thf)2] and revealed an Fe(II) species in a quartet ground state.

Reaction of hydroxyamide-functionalized azolium salt with Ag2O: Three different transformations

We report three different transformations in the reaction of the hydroxyamide-functionalized azolium chloride 1 with Ag2O. These transformations were controlled by the N-substituent at the azolium ring of 1. Treatment of 1c (R = Me, alkyl) with Ag2O afforded the corresponding monodentate NHC-Ag (NHC represents N-heterocyclic carbene) complex, 6c, in 95% yield. In contrast, the reaction of 1b (R = Ph, aryl) with Ag2O yielded the corresponding 2-hydroxyoxazolidine-substituted azolium hydroxide, 7b, in 90% yield. In this transformation, perhaps the cyclization of the hydroxyamide moiety of 1b to 2-hydroxyoxazolidine occurred under the influence of the hydroxide counter anion. Several aryl-substituted azolium chlorides, 1d-f, were also converted into the corresponding cyclization products, 7d-f. However, the reaction of 1h (R = 2,4,6-Me3C6H2, aryl) with Ag2O afforded the corresponding NHC-Ag complex, 6h, in 93% yield, whereas the reaction of 1i (R = 4-MeOC6H4, aryl) with Ag2O provided a mixture of 6i and 7i in 56% and 32% yields, respectively. Moreover, the reaction of azolium chloride, 1j (R = 2,6-iPr2C6H3, aryl), which has a more sterically hindered substituent at the ortho-position of the aryl side-arm, was investigated. Treatment of 1j with Ag2O gave unexpected urea derivative, 8j, in 99% yield.

New trivalent phosphorus containing poly(arylene ether)s as alternative reactants for the Mitsunobu reaction

Novel phosphine containing poly(arylene ether)s with trivalent phosphorus are prepared by reaction of bis(4-fluorophenyl) phenylphosphine with 2,2-bis(4-hydroxyphenyl)propane. The reaction conditions are adjusted to avoid partial oxidation of the phosphine derivative during polycondensation. Solution polycondensation results in copolymers with phosphine and phosphorus oxide containing repeating units with high molar contents of phosphine oxide (up to 45 mol% P = O repeating units), while solvent-free melt polycondensation of bis(4-fluorophenyl) phenylphosphine with bis(trimethylsilyl)-2,2-bis(4-oxyphenyl)propane and CsF as catalyst yields 85 mol% phosphine containing repeating units. The weight-averaged molar masses are in the range of 40,000 g/mol.The phosphine containing polymers are used, to illustrate an example, as polymeric reagent in the Mitsunobu reaction for the etherification of 5-hydroxyisophthalic acid dimethylester with henicosaperfluoroicosanol to yield a monomer for semifluorinated polyesters. The Mitsunobu reaction requires triaryl phosphine derivatives as reactants which are oxidized to phosphorus(V) compounds during the course of the reaction. The separation of the oxidized products in the reaction with triphenyl phosphine (TPP) is generally complicated and the application of the novel poly(aryl ether)s results in simplification of the work-up and increase of the yield of the desired product (33% with TPP vs. 55% with the phosphine containing poly(aryl ether) P13). Thus, the applicability of the polymers as polymer-supported phosphine derivatives replacing low molar mass phosphines is demonstrated.

МЕХАНІЗМИ РЕАКЦІЇ 14C(11B,10В)15С ЗА ЕНЕРГІЇ 45 МеВ ДЛЯ ОСНОВНИХ І ЗБУДЖЕНИХ СТАНІВ ЯДЕР 10В І 15С

New experimental data for differential cross-sections of the reaction 14C(11B,10B)15C at Еlab(11B) = 45 MeV were obtained for transitions to the ground and excited states of the exit reaction channel nuclei. The experimental data were analyzed within the coupled-reaction-channels method (CRC). The 14C + 11B elastic scattering channel as well as channels for one- and two-step transfers of nucleons and clusters were included in the coupling scheme. The Woods - Saxon (WS) potential was used in the CRC-calculations for the entrance reaction channel with the parameters deduced previously from the analysis of the experimental data of 11B + 14C elastic and inelastic scattering, whereas the WS potential for the exit 15C + 10B reaction channel was deduced from the fit of CRC cross-sections to the 14C(11B,10B)15C reaction experimental data. Needed for CRC-calculations spectroscopic amplitudes (factors) of the nucleons and clusters transferred in the reaction were calculated within the translational-invariant shell model. The mechanisms for one- and two-step transfers of nucleons and clusters were investigated in this reaction. The 15C + 10B potential parameters were deduced, and comparisons of the CRC reaction cross-sections calculated with the 15C + 10B and 12,13C + 10B potential parameters were performed. The differences between these CRC calculations were observed, e.g. "isotopic effects" were observed for the potentials of 10B interaction with 12,13,15C carbon isotopes.
