Wu, Liqiang published the artcileSynthesis of 6-bromoquinolines using benzyltrimethylammonium tribromide, Category: bromides-buliding-blocks, the publication is Youji Huaxue (2010), 30(8), 1250-1254, database is CAplus.
Several 6-bromoquinoline derivatives were designed and the synthesis of the target compounds was achieved in high yield by a reaction of 2-aminobenzophenone [i.e., (2-aminophenyl)(phenyl)methanone] with α-methylene carbonyl compounds in the presence of benzyltrimethylammonium tribromide as a phase-transfer catalyst in acetonitrile at room temperature and the products thus obtained were confirmed by 1H-NMR, 13C-NMR spectra and elemental anal. The title compounds thus reported included 8-bromo-10-phenyl-11H-indeno[1,2-b]quinolin-11-one, 2-bromo-12-phenylbenz[b]acridine-6,11-dione and 6-bromo-4-phenylquinoline derivatives, 7-bromo-9-phenyl-1H-cyclopenta[b]quinoline derivatives, etc.
Youji Huaxue 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 C5H8N2O, Category: bromides-buliding-blocks.
