Synthesis and Properties of N-Bromosuccinimide Derivatives of Ammonium Dialkyl/Alkylene Dithiophosphates

Abstract

Reactions of N-bromosuccinimide with ammonium salt of alkylene (dialkyl) dithiophosphates; [; G = ─CMe 2 CMe 2 ─CH 2 CMe 2 CH 2 -, CMe 2 CH 2 CHMe-, CH 2 CH 2 CHMe-; (RO) 2 PS 2 NH 4 ; R = C 2 H 5 , n-C 3 H 7 , i-C 3 H 7 ] in 1:1 molar ratio in refluxing benzene solution yields red/brown-colored sticky liquids. These newly synthesized complexes have been characterized by physicochemical and spectroscopic techniques (MW, IR, and NMR [ 1 H and 31 P]). The computational semi-empirical calculations (MOPAC6P/c) have also been studied for these complexes. On the basis of above studies, the formation of P-S-N chemical linkage has been established.
