Fox, G. J. et al. published their research in Organic Syntheses in 1976 | CAS: 615-55-4

3,4-Dibromoaniline (cas: 615-55-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Name: 3,4-Dibromoaniline

para-Bromination of aromatic amines: 4-bromo-N,N-dimethyl-3-(trifluoromethyl)aniline was written by Fox, G. J.;Hallas, G.;Hepworth, J. D.;Paskins, K. N.. And the article was included in Organic Syntheses in 1976.Name: 3,4-Dibromoaniline This article mentions the following:

Treatment of m-F3CC6H4NMe2 with 2,4,4,6-tetrabromo-2,5-cyclohexadien-1-one (from 2,4,6-Br3C6H2OH and Br) in CH2Cl2 gave 82-90% 4,3-Br(F3C)C6H3NMe2. Twenty-eight addnl. arom amines, e.g., 2-ClC6H4NH2, PhNH2, 1-naphthylamine, and o-anisidine, were para brominated in a similar manner. In the experiment, the researchers used many compounds, for example, 3,4-Dibromoaniline (cas: 615-55-4Name: 3,4-Dibromoaniline).
