Synthetic and Spectroscopic Studies on Some Bis(dialkyldithiocarbomato)-arsenic(III) O,O'-dialkyldithiophosphates

Abstract

The reactions of bis(dialkyldithiocarbamato)arsenic(III) chloride with sodium salts of dialkyldithiophosphates in 1:1 molar ratio give the corresponding mixed derivatives of the type [R2NCS2]2AsS2P(OR′)2 [where, R = CH3 and C2H5; R′ = Et, Pr n , Pr i , Bu n and Bu i ]. These derivatives are yellow crystalline solids or yellow viscous liquids. All these newly synthesized derivatives are soluble in common organic solvents such as benzene, chloroform, carbondisulphide, acetone, and dichloromethane. These derivatives have been characterized by melting points (only solid derivatives), elemental analysis (C, H, N, S, and As) as well as spectral IR, NMR [1H, 13C, and 31P] studies. Based on these studies tentative structures for these derivatives have been proposed.
