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

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