Abstract Under the influence of nitrosylsulfuric acid, 5- and 6-bromo-substituted 2-amino-1-methylbenzimidazoles are converted, as a result of self-coupling, to, respectively, 2′,5- and 2′,6-azobenzimidazoles, which are resistant to reductive cleavage. 5,6-Dibromo-2-amino-1-methylbenzimidazole forms similarly constructed azo compounds by splitting out of one of the bromine atoms. The behavior of bromo-substituted 2-aminobenzimidazoles toward nitrosylsulfuric acid in the presence of arenes was studied.
