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.
