Synthesis and Characterisation of Mixed Dithiolatoarsenic(Iii) Alkyldithiocarbonates and Dialkyldithiocarbamates

Abstract

Mixed dithiolatoarsenic (III) alkyldithiocarbonate and dialkyldithiocarbamate derivatives of the type SCH₂CH₂SAs(S₂COR), [where R = Et, Prⁿ, Prⁱ, Buⁿ & Buⁱ] and SCH₂CH₂SA_s(S₂CX), [where X = NMe₂, NEt₂ and N(CH₂CH₂)₂] are reported. These are synthesised by the simple replacement reactions of 2-chloro-1,3-dithia-2-arsacyclopentane with potassium alkylxanthate and with sodium dialkyldithiocarbamate in 1:1 molar ratios in benzene respectively. These derivatives have been characterised by elemental analyses, melting point determinations as well as IR & NMR (¹H and ¹³C) spectral studies and tentative structures have been proposed.
