An　electrochemical　dehydrogenative　amination　for　the　synthesis　of　benzimidazoles　was　developed.　This　electrosyn-thesis　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　tran-sition　metals　and　oxidants.　Under　undivided　electrolytic　conditions,　various　benzimidazole　derivatives　could　be　synthesized,　exhibiting　functional　group　tolerance.
