Synthesis and characterization of some toluene-3,4-dithiolatobismuth(III) alkyl dithiocarbonates

Some mixed toluene-3,4-dithiolatobismuth(III) alkyl dithiocarbonate derivatives of the type SC6II3(CH3)SBiS2COR (where R = Me, Et. n-Pr, i-Pr n-Bu, and i-Bu) have been synthesized by the reaction of the potassium salts of alkyl dithiocarbonates and toluene-3,4-dithiolatobismuth(ill) chloride in equimolar ratio in an anhydrous carbon disulfide/acetone mixture. These newly synthesized derivatives have been characterized by elemental analyses, melting point determinations, as well as IR and NMR spectral studies. On the basis of these studies, tentative structures for these derivatives have been proposed.
