Kakinami, Takaaki published the artcileHalogenation using quaternary ammonium polyhalides. XXV. Bromination of acetanilides with benzyltrimethylammonium tribromide-zinc chloride system, Formula: C10H16Br3N, the publication is Nippon Kagaku Kaishi (1990), 705-8, database is CAplus.
The reaction of acetanilides with equimolar amounts of PhCH2N+Me3 Br3– and ZnCl2 in AcOH under mild conditions gave the bromo-substituted acetanilides in good yields. E.g., AcNHC6H3Me2-3,5 gave 99% AcNHC6HBr2Me2-2,4,3,5.
Nippon Kagaku Kaishi published new progress about 111865-47-5. 111865-47-5 belongs to bromides-buliding-blocks, auxiliary class Benzenes, name is Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, and the molecular formula is C10H16Br3N, Formula: C10H16Br3N.
