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

2-Mercapto-2-thiono-1,3,2-dioxaphospholanes and dioxaphosphorinanes, have been synthesized by the reactions of phosphorus pentasulphide with some 1,2-diols (viz., butane-2,3-diol and 2,3-dimethylbutane-2,3-diol) and 1,3-diols (viz., 2-methylpentane-2,4-diol, 2,2-dimethylpropane-1,3-diol and 2,2-diethylpropane-1,3-diol) in 1:2 molar ratio in dry benzene. These volatile compounds have been purified by distillation under reduced pressure. The 2-methylpentane-2,4-diol derivative, however, decomposed during attempted distillations. These new compounds have been characterized by elemental analysis, molecular weight determinations, measurement of pK a values and IR as well as NMR spectroscopic studies. The ammonium and sodium salts of some of these acids have also been characterized.

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

Mixed chloride dialkyldithiophosphates of bismuth(III), [(RO)2PS2] n BiCl3-n (n = 1, 2; R [dbnd] Et, Pr n , Pr i and Bu i ) have been synthesized for the first time by the reactions of bismuth trichloride with sodium diisopropyldithiophosphate or alternatively by co-disproportionation reactions of bismuth trichloride with bismuth tris(dialkyldithiophosphates) in different stoichiometric ratios in suitable organic solvents. Monohalobismuth bis(diisopropyldithiophosphates) have also been synthesized by the cleavage reactions of bismuth tris(dialkyldithiophosphates) with bromine or iodine in 2:1 molar ratio. These new derivatives have been characterized by elemental analysis, molecular weight determinations (both cryoscopic and ebullioscopic) as well as spectroscopic (IR, 1H NMR and 31P NMR) studies. On the basis of these data chelated structures with bidentate dialkyldithiophosphate groups have been proposed for these monomeric derivatives. Hydrolysis reactions of some of these compounds have also ...

Synthesis and reactions of mixed halide dialkyldithiophosphate derivatives of bismuth(iii)

Compounds of the type G-O-O-AsS2P(OR)2 (G = -CH2CH2-, -(CH3)CHCh2, -(CH3 -(CH3)2CC(GH3)2- and -CH2CH[dbnd]CHCH2 - and R [dbnd] C2H5, n-C3H7, i-C3H7, sec.-C4H9 and C6H5 have been synthesized by the reactions of 2-chloro-1,3,2-diox-arsolanes and -arsenanes with sodium, lead and ammonium salts of dialkyldithio-phosphoric acids in stoichiometric ratios. These new derivatives have been characterized by elemental analyses and molecular weight determinations. Attempts have been made to elucidate the structure of these compounds by their IR and NMR spectra.
