Synthesis and Properties of 2-Alkylene/Dialkyl Dithiophosphato-2-oxo-1,3,2-dioxaphosphorinanes

Reactions of 2-chloro-2-oxo-1,3,2-dioxaphosphorinanes with ammonium alkylene/dialkyl dithiophosphates in a 1:1 molar ratio in refluxing benzene solution yields nonvolatile, yellow viscous liquids of the type (S)S(O) and (RO)2 P(S)S(O) , respectively. [G = ‒ CH2CH2CHCH3‒,. ‒ C(CH3)2CH2CHCH3‒,. ‒ CH2C(CH3)2CH2; R = i-C3H7, C2H5]. These compounds are hygroscopic and monomeric in nature. The newly synthesized derivatives have been characterized by physicochemical and spectroscopic techniques (IR, NMR [1H&31P], and M.W).
