An electrochemical dehydrogenative amination for the synthesis of benzimidazoles was developed. This electrosynthesis method could address the limitations of the C(sp3)-H intramolecular amination synthesis reaction and provide novel access to obtain 1,2-disubstituted benzimidazoles without transition metals and oxidants. Under undivided electrolytic conditions, various benzimidazole derivatives could be synthesized, exhibiting functional group tolerance.

Cu-Mn B (a heterogeneous catalyst) catalyzed synthesis of 1-benzyl-2-phenyl-1H-benzo[d]imidazoles is reported. In this reaction, 2-phenyl-1H-benzo[d]imidazoles are found to be the side products. The reported protocol is simple and highly efficient, tolerates a wide variety of substrates and the products were formed in good to excellent yield.
