Abstract
Depending on the nature of the substituent in the 2 position of the heteroring, imidazo[1,2-a] benzimidazole derivatives undergo either mononitration in the 3 position or form dinitro derivatives. In the latter case, one nitro group enters the phenyl group in the 2 position, and the other enters the benzimidazole fragment of the molecule.
