Kajigaeshi, Shoji published the artcileOxidation using quaternary ammonium polyhalides. IV. Selective oxidation of sulfides to sulfoxides with benzyltrimethylammonium tribromide, Recommanded Product: Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Bulletin of the Chemical Society of Japan (1989), 62(10), 3376-7, database is CAplus.
The reaction of sulfides with a stoichiometric amount of benzyltrimethylammonium tribromide and aqueous sodium hydroxide in dichloromethane at room temperature or in 1,2-dichloroethane under reflux gave the corresponding sulfoxides in good yields.
