Conditions that exclude "self-coupling" in the reaction of benzimidazole-2-diazonium salts with the simplest aromatic hydrocarbons were selected.The synthesis of 3'-tolyl- and 2'-6'-xylylazobenzimidazoles, which are isolated along with the expected isomers in diazo coupling with toluene and m-xylene, was also realized by an alternative pathway from the corresponding p-aminophenylazobenzimidazoles.The reaction of benzimidazole-2-diazonium salts with primary aromatic amines, which is complicated in the benzimidazole series by side reactions, was studied.The structures of the newly synthesized compounds were confirmed by spectral methods.
