Description
Summary:Phosphorus trichloride and thiophosphoryl chloride derivatives of alkylene dithiophosphates of the type PCl 3 − n ( ) n and P(S)Cl 3− n ( ) n (where G = -CH 2 CH 2 CHMe-, -CMe 2 CMe 2 -, -CH 2 CH 2 CH 2 CH 2 - and -CMe 2 CH 2 CHMe-, n = 1, 2, 3] have been synthesized for the first time by reacting the ammonium salt of alkylene dithiophosphoric acid with phosphorus trichloride and thiophosphoryl chloride in different stoichiometric ratios under anhydrous reaction conditions. The newly synthesized derivatives are either colorless liquids or viscous semisolids, hygroscopic in nature and are soluble in common organic solvents. These are characterized by elemental analysis, molecular weight determinations and physicochemical studies IR, NMR ( 1 H and 31 P). On the basis of above studies the formation of P-S-P and S = P-S-P(S) chemical linkages have been established. 231 P NMR studies provide convincing evidence regarding the chemical bonding mode in these derivatives.
