S. Goel et al., KINETICS AND MECHANISM OF THE OXIDATION OF ORGANIC SULFIDES BY BENZYLTRIMETHYLAMMONIUM TRIBROMIDE, Journal of chemical research. Synopses, (12), 1996, pp. 510
The oxidation of organic sulfides by benzyltrimethylammonium tribromid
e involves formation of a halogenosulionium cation in the slow step an
d its subsequent decomposition in the fast step to give sulfoxides.
