Substitution Reactions of Mono- and Trichloro Acetic Acids with Ammonium Dialkyl (Alkylene) Dithiophosphates

Abstract

A reaction of mono- and trichloro acetic acid with ammonium salts of alkylene (dialkyl) dithiophosphate; [S₂NH₄; G = ─CH₂CH₂CHMe─, ─C(Me)₂C(Me)₂─, ─CH₂C(Me)₂CH₂─, and ─C(Me)₂CH₂CHMe─; (RO)₂PS₂-NH₄; and R = C₂H₅, C₃H₇, i-C₃H₇;] in a 1:1 molor ratio in refluxing benzene solution yields low melting solids and light-yellow oily liquids of the type [(RO)₂PS₂R' and S₂R′, where R′ = CH₂COOH and Cl₂CCOOH], which are hygroscopic in nature. These newly synthesized complexes have been characterized by physicochemical and spectroscopic techniques (MW, IR, ¹H, and ³¹PNMR) On the basis of the previously discussed studies, the formation of a P─S─C chemical bond has been established.
