Abstract Vilsmeier formylation of 1,2-diphenylimidazo[1,2-a]benzimidazole leads to the 3-formyl derivative, while heating with acetic anhydride in sulfuric acid gives the 3-acetyl derivative. The nitration of this benzimidazole with potassium nitrate in sulfuric acid gives a mixture of mono-, di-, and trinitro derivatives. Bromination in chloroform leads to a mixture containing the mono- and dibromo derivatives. The structures of the compounds obtained were confirmed by their IR, PMR, and mass spectra.
