Bismuth(III) Chloride Graphite Intercalation Compounds: Preparation and Characterization of the First Stage Compound

In dependence on the pressure of chlorine (1 to 14.5 bar) xe prepared grephite interceletion compounds from BiCl 3 melts (T=523K) The compounds were characterized by X-ray diffraction of the 00l and hk pattern. We obtained first (identity period in c direction: 971 pm a=904 pm, b=1935 pm, γ=89.8 o , S a =28.3 o ) and second stage compounds. X-ray absorption measurements at the Bi-L III edge showed a decrease in the Bi-Cl bond length from 250 pm to 245 pm. The edge is shifted about 0.8 eV to lower energies in comparison to pure BiCl 3

Corrosion Inhibition of Cobalt in Some Acid Solutions by Bismuth(III) Chloride

Inhibition effects of bismuth(III) chloride on cobalt corrosion in 1N , 1N , and 1N were investigated by polarization measurements and colorimetry of dissolved cobalt ion. More than 85% of the inhibition efficiency was obtained for cobalt in these acid solutions. X‐ray photoelectron spectra showed the formation of a protective film which comprises an inner layer composed of metallic bismuth and an outer layer of cobalt(II), bismuth(III), chloride, oxide, and hydroxide ions. Because the cathodic bismuth deposition was stimulated and a uniform layer of bismuth was not formed on the surface, the corrosion reaction was accelerated in 1N at a high concentration of the inhibitor. The inhibition efficiency of the compound for various metals in 1N was confirmed as being associated with a difference in the standard electrode potential between bismuth and a metal.

Bismuth(III) complexes with sulfur and selenium donor ligands: synthesis and crystal structures of BiCl3·Prn2P(S)P(S)Prn2and [(Me2N)3PSeSeP(NMe2)3]2+[(BiCl4)2]n2n–

Direct addition of bismuth(III) chloride and tetra-n-propyldiphosphane disulfide gave bright yellow crystals of the 1 : 1 adduct BiCl3·Prn2P(S)P(S)Prn2. An X-ray crystallographic investigation reveals a halide-bridged dimeric structure in which each bismuth atom is surrounded by an essentially octahedral arrangement of four chlorine [two terminal. Bi–Cl 2.500(5), 2.516(5), and two bridging, Bi–Cl 2.653(4). 3.015(5)Å] and two sulfur atoms [Bi–S 2.857(4), 2.973(4)Å]. Each of the two ligand molecules is involved in bidentate (S,S′) chelation to a bismuth atom to form a five-membered ring. Crystals are monoclinic, space group P21n, with a= 10.127(6), b= 16.057(6), c= 13.843(6)Å, β= 93.3(1)°, Z= 4. The reaction of BiCl3and tris(dimethylamino)phosphane selenide in acetonitrile gave the yellow crystalline salt [(Me2N)3PSeSeP(NMe2)3]2+[(BiCl4)2]n2n– as identified by a crystal structure determination. Formation of the unusual cation follows from air oxidation of the organophosphine selenide in the presence of BiCl3. The Se–Se bond distance is 2.309(5)Å and the torsion angle P–Se–Se–P is –112.4(4)°. For the anion, linkage of dimeric (BiCl4)2 units via further halide bridging results in an infinite chain structure of edge-shared octahedra. Crystals are triclinic, space group P with a= 7.386(6), b= 12.813(8), c = 18.919(8)Å, α= 76.0(1 ), β= 78.9(1 ), γ= 73.2(1)° and Z= 2.

Metallkomplexe in Biologie und Medizin, VI. Darstellung und Kristallstruktur von (Penicillaminato‐O,S,N)bismut(III)1‐chlorid

Metal Complexes in Biology and Medicine, VI[1]. – Synthesis and Structure of (Penicillaminato‐O,S,N)bismuth(III) ChlorideBismuth(III) oxychloride reacts with D‐(–)1‐penicillamine to form [D‐(–)1‐penicillaminato‐O,S,N]bismuth(III) chloride (1), the solid state structure of which has been determined by single‐crystal X‐ray diffraction. The tridentate chelation of the metal center by sulfur, nitrogen, and oxygen atoms leads to the formation of five‐membered rings. Due to interaction of bismuth with oxygen atoms of the carboxy groups, a polymeric two‐dimensional structure results in the crystal lattice. Bismuth has a seven‐fold inner coordination sphere.

New effective catalysts for Mukaiyama-aldol and -Michael reactions: bismuth trichloride-metallic iodide systems

Metallic iodide-activated bismuth(III) chloride efficiently catalyzes the Mukaiyama-Aldol and -Michael reactions. Some examples of reactions of silyl enol ethers derived from acetophenone and cyclohexanone (1 and 2, respectively) with aldehydes, ketones, acetals, and α-enones are given. The cross-over aldolization between 1 and benzaldehyde in the presence of BiCl 3 -1.5ZnI 2 or BiCl 3 -1.5SnI 2 systems (5% mol) has been carried out quantitatively at -30 and -78 o C, respectively

Glycosylation Based on Phosphite Chemistry

1-Glycosyl dimethyl phosphite was found to be promising as a new glycosyl donor for glycosylation, and some catalysts such as zinc chloride, zinc chloride-silver perchlorate, bismuth chloride, and methyl trifluoromethanesulfonate were found to promote the reaction.

無電解めっきによるビスマス皮膜の形成

Electroless deposition of bismuth has been achieved, probably for the first time, using stannous chloride as a reducing agent. Bismuth films were autocatalytically deposited on aluminum substrate activated with palladium at a rate of 1.84mg·cm-2·h-1.Optimum bath composition were 0.08M, 0.34M, 0.20M, 0.08M and 0.04M for bismuth trichloride, trisodium citrate, NTA, disodium EDTA and stannous chloride, respectively. Rapid film deposition was obtained at pH8.8 and 60°C.The films were grown to the desired thickness by renewing the plating bath every 30 minutes.It was observed from X-ray analysis and X-ray fluorescence spectrometry that the crystal structure of deposited film was not affected by the plating conditions, and that it contained no trace of tin.UV absorption spectra of the plating bath showed that the EDTA formed complex salts with Bi3+, Sn2+, and Sn4+, while the citric acid and NTA served as solvents for the insoluble complex salts formed by EDTA with Sn2+ and Sn4+.

Synthesis and Reactions of Some Crowded Triorganylbismuthines

Abstract Bismuth trichloride reacts smoothly with mesityl- and 2,4,6-triisopropylphenylmagnesium bromides in boiling tetrahydrofuran to form the corresponding triarylbismuthines in good yields, while a similar reaction with 2,4,6-triisopropylphenylmagnesium bromide halts at diarylation stage, giving chlorobis(2,4,6-triisopropylphenyl)bismuthine as the sole product. Several crowded alkyl-, alkenyl-, and alkyn-yldiarylbismuthines have been prepared from the above diarychlorobismuthine through the reaction with an appropriate organolithium reagent.

The inhibition of iron corrosion in acid solutions using bismuth(III) chloride

Corrosion inhibition effects of bismuth(III) chloride on iron in 1 N HClO 4, 1 N HCl and 1 N H 2SO 4 were investigated by polarization measurements. The high inhibitor efficiencies obtained are attributed to the formation of a protective film on the iron surface. The persistence of the film was examined in an acid solution without inhibitors by impedance measurements. The film is more persistent than the films formed from tri-ethylstibine and tri-ethylbismuthine which have been examined previously. The homogeneity in appearance and uniform distributions of the elements, Fe and Bi on the iron surface were confirmed by EPMA. X-Ray photo-electron spectra showed that the protective film consists of two layers, an outer layer composed of ferrous and bismuthous oxides and an inner layer of metallic bismuth. The high efficiency of the inhibitor is mainly ascribed to the outer layer and the marked persistence of the film to the inner layer.

A persistent corrosion-protective film formed on iron in acid solutions with triethylbismuthine

Triethylbismuthine, an organic bismuth compound, was examined as a corrosion inhibitor for iron in 1 N HClO 4, 1 N HCl and 1 N H 2SO 4 by polarization and impedance measurements. This inhibitor is less effective for iron corrosion in acid solutions than the corresponding antimony compound which has previously been tested. However, the protective film formed on the iron surface by treatment with this compound in 1 N HClO 4 is more persistent in the protection of iron against acid corrosion than that formed with the antimony compound. The protective film comprises a monolayer of the inhibitor and anion adsorbed at the solution interface and a film with an outer layer composed of ferrous oxide containing small amounts of bismuth oxide and chloride ion and an inner layer of metallic bismuth. The high persistence of the protective film arises from this inner layer.

The catalytic cross aldol reaction between a silyl enol ether and an aldehyde has been applied to the furane series giving the ketols RCOCH2CHOHR' (R or R′ = 2-furyl). Good results (with no resinification or crotonisation) have been obtained using bismuth trichloride in presence of sodium iodide as catalyctic system, which allows to insulate the intermediaire silylated derivatives.

Bismuth Trichloride as a New Efficient Catalyst in the Aldol Reaction and the Michael Reaction

Abstract In the presence of a catalytic amount of bismuth(III) trichloride (5 mol%), silyl enol ethers react with aldehydes at room temperature in dichloromethane to give the corresponding aldols in good yields. Silyl enol ethers also have been found to react with α,β-unsaturated ketones at room temperature in dichloromethane to afford the corresponding 1,5-dicarbonyl compounds, the Michael adducts in good yields. The intermediate adducts of the aldol reaction (the silyl ethers) and the Michael reaction (the silyl enol ethers) were also obtained in good yields.

Sterically crowded aryl bismuth compounds: synthesis and characterization of bis{2,4,6-tris(trifluoromethyl)phenyl} bismuth chloride and tris{2,4,6-tris(trifluoromethyl)phenyl} bismuth

The reactions of BiCl 3 with 2,4,6-tris(trifluoromethyl)phenyl lithium (LiR f) in ether solution in 1 : 2 and 1 : 3 ratios have led to the isolation of Bi(R f) 2Cl ( I) and Bi(R f) 3 ( II). The hexane-soluble compounds have been spectroscopically and structurally characterized I: monoclinic space group P2 1/ c, a = 8.816(2), b = 30.459(6), c = 8.817(2)Å, β = 109.58(2)°, Z = 4, V = 2230.7(8)Å 3; II: monoclinic space group P2 1/ c, a = 11.769(2), b = 17.029(3), c = 16.213(3)Å, β = 102.74(3)°, Z = 4, V = 3169.3(10)Å 3. Both compounds are monomeric in the solid state. Compound II is unstable in solution even under inert atmosphere producing R fH. In the solid state the compound is stable in inert atmosphere but decomposes slowly upon exposure to air producing R fOH and (R f) 2O. In the presence of BiCl 3, II undergoes exchange to produce I and another complex which is probably Bi(R f)Cl 2.
