Abstract:

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  /></span>(S)S(O)<span class= /></span> and (RO)<sub>2</sub> P(S)S(O) <span class= /></span>, respectively. G = ? CH<sub>2</sub>CH<sub>2</sub>CHCH<sub>3</sub>?,. ? C(CH<sub>3</sub>)<sub>2</sub>CH<sub>2</sub>CHCH<sub>3</sub>?,. ? CH<sub>2</sub>C(CH<sub>3</sub>)<sub>2</sub>CH<sub>2</sub>; R = i-C<sub>3</sub>H<sub>7</sub>, C<sub>2</sub>H<sub>5</sub>].</p> These compounds are hygroscopic and monomeric in nature. The newly synthesized derivatives have been characterized by physicochemical and spectroscopic techniques (IR, NMR <sup>1</sup>H&<sup>31</sup>P], and M.W).</td>
