Islam, A. M. published the artcileHalogenation of substituted anilines with halogen acids and hydrogen peroxide, Name: 4-Bromo-2-chloro-6-nitroaniline, the main research area is aniline halogenation; haloaniline preparation.
To a solution of substituted nitroaniline, EtOH and HCl (or HBr) was added 27.2% H2O2, the whole stirred 1 hr at 50°, filtered from any formed dihalogen derivatives, and the filtrate diluted with 100 ml H2O to give the corresponding mono halogenated product. The dihalogenated products were prepared by doubling the acid concentration in the above experiment The mono- and dihalogenated products (I) prepared were (R1, R2, R3, and R4 given): H, Cl, H, NO2; Cl, Cl, H, NO2; H, Br, H, NO2; Br, Br, H, NO2; Cl, Br, H, NO2; H, NO2, H, Cl; Cl, NO2, H, Cl; H, NO2, H, Br; Br, NO2, H, Br; Br, NO2, H, Cl; Cl, NO2, H, Br; Br, H, NO2, H; Br, H, NO2, Br; Cl, H, NO2, Cl. 4-Nitroaniline, 27.2% H2O2, 50% H2SO4 stirred 2 hr at room temperature gave 4,4′-dinitroazobenzene.
United Arab Republic Journal of Chemistry published new progress about Halogenation. 34033-41-5 belongs to class bromides-buliding-blocks, name is 4-Bromo-2-chloro-6-nitroaniline, and the molecular formula is C6H4BrClN2O2, Name: 4-Bromo-2-chloro-6-nitroaniline.
