Spectroscopic and elemental analysis studies of the reactions of triiodomethane with dialkyl and alkylenedithiophosphate Salts and acids

Abstract

Methyl tris-dialkyl and alkylenedithiophosphates, HC[S2P(OR)2]3 where R = Et, n-Pr, i-Pr, i-Bu and Ph and HC[S2POGO]3, where G = -CMe2, CMe2, -, CH2CMe2CH2-, and -CH2CEt2CH2-, have been synthesized for the first time by the reactions of iodoform with the alkali metal salt of the corresponding ligand in anhydrous toluene in 1:3 molar ratio respectively. These compounds are powdery solids or viscous liquids and are soluble in common organic solvents, in which they show monomeric behavior. Based on elemental analyses, molecular weight determinations, IR and NMR (1H and 31P) spectral data, chelate tetrahedral structures have been proposed for these derivatives
