Alkylenedithiophosphate derivatives of arsenic(III), antimony(III) and bismuth(III)

Tris(alkylenedithiophosphates) of arsenic(III), antimony(III) and bismuth(III), ▪ have been synthesized by the reactions of alkylenedithiophosphoric acids with metal oxides and chlorides and of their ammonium salts with metal chlorides in suitable solvents. Mixed chloride alkylenedithiophosphates of arsenic(III) and antimony(III), ▪ have been obtained by the reactions of metal chlorides with ammonium alkylenedithiophosphates at 1 : 1 and 1 : 2 molar ratios or alternatively by the co-disproportionations reactions of metal chlorides with metal tris(alkylenedithiophosphates) at different (2 : 1 and 1 : 2) molar ratios. These new compounds have been characterized by elemental analyses, molecular weight measurements and spectroscopic (IR, and 1H and 31P NMR) data. Chelated structures with bidentate alkylenedithiophosphate groups have been proposed for all these derivatives.

Mixed halide dialkyldithiophosphate derivatives of arsenic(III) and antimony(III)

Mixed chloride dialkyldithiophosphates of arsenic(III) and antimony(III), [(RO) 2PSS] n MCl 3−n (M = As, Sb; n = 1, 2; R = C 2H 5, n-C 3H 7, i-C 3H 7 and i-C 4H 9) have been synthesized for the first time by the reac metal chlorides with sodium dialkyldithiophosphates or alternatively by co-disproportionation reactions of metal chlorides with metal tris(dialkyldithiophosphates) in different stoichiometric ratios. Mixed halide dialkyl-dithiophosphates of antimony(III) have also been prepared by the cleavage reactions of antimony tris(diisopropyldithiophosphate) with bromine or iodine. Hydrolysis reactions of a few of these compounds have also been studied. The new compounds have been characterized by elemental analyses, molecular weight determinations (cryoscopic) as well as IR and NMR ( 1H, 31P) data; chelated structures with bidentate dialkyldithiophosphate groups are proposed.

Some trimethylphosphineoxide complexes of lanthanide and indium tris-(bis-trimethylsilylamides)

The reactions of the 3-coordinated metal tris-(bis-trimethylsilylamides) M[N(SiMe 3) 2] 3 (ML 3; where M = La, Pr, Eu, Gd and In) with trimethylphosphineoxide Me 3PO(L′) have been studied. All of these metals gave 1:1 complexes ML 3(L′) which dissociated on heating in vacuo. The Pr and Eu complexes gave interesting pseudo-contact shifted 1H NMR spectra which are qualitatively in accord with the expected molecular structure. Variable temperature NMR measurements proved the restricted rotation of the silylamide (L) ligands occurs around the M–N axes. Evidence is also presented for unstable 5-coordinated complexes ML 3(L′) 2. The gadolinium 1:1 complex gave a very broad NMR spectrum and its ESR spectrum is being investigated.

Improvement of optical purity of metal tris-(1,10-phenanthroline) chelates by use of adsorption on a colloidal clay

When the clay–metal adducts are filtered through a membrane filter from a solution containing sodium montmorillonite (3.3 × 10–4M cation exchange sites), 3.4 × 10–4M(+)546-[Ni(phen)3][ClO4]2, and 1.7 × 10–4M(–)546-[Ni(phen)3][ClO4]2, the filtrate contains 1.2 × 10–4M(+)546-[Ni(phen)3][ClO4]2 and 0.2 × 10–4M(–)546-[Ni(phen)3][ClO4]2(phen = 1,10-phenan-throline); this improvement in optical purity results from the adsorption of the racemic metal chelate on the clay surface.

Inhibition of hydrocarbon oxidation by trivalent metal tris(N,N-diethyldithiocarbamates)

1. The Sb and Bi dithiocarbamates inhibit the low-temperature initiated oxidation of ethylbenzene. Similarities with the inhibiting action of the divalent metal dithiocarbamates suggest that the inhibition mechanism is the same in both cases. 2. Oxidation potentials have been measured for the Cr(III), Fe(III), Mn(III), Sb(III), and Bi(III) dithiocarbamates. 3. The inhibiting action of the M(Dtc)3 differs from that of the M(Dtc)2 insofar as that it cannot be correlated with the oxidation potential. This is obviously due to the fact that these complexes have octahedral structure, the tendency of the chelate toward ligand exchange reactions being the principal factor in RO 2 . complexing.

Equilibria in complexes ofN-heterocyclic molecules, Part XV+. Intermediates in the reaction of cyanide with transition metal tris complexes of 1,10-phenanthroline, 5-nitro-1,10-phenanthroline and 2,2'-bipyridyl

The Ru(phen)3(CN)2 · 6 H2O, Ru(bipy)3(CN)2 · 6H2O, Fe(phen)3(CN)2 · H2O and Ru(5-NO2P)3(CN)2 · 2 H2O compounds have been isolated during the reaction of the parent cations with aqueous cyanide solutions. It is evident, that in each case, attack at the ligand has taken placevia the cyanide nucleophile, though the equilibrium constant for the formation of the Reissert-type species are widely different. The implications of the findings with respect to the known reaction kinetics of the parent ions in aqueous cyanide solution are discussed.
