Catalyst‐Free Electrosynthesis of Benzimidazolones through Intramolecular Oxidative C−N Coupling

Catalyst‐Free Electrosynthesis of Benzimidazolones through Intramolecular Oxidative C−N Coupling

The electrochemical synthesis of N, N’‐disubstituted benzimidazolones from ureas through an intramolecular anodic dehydrogenative N−H/C−H coupling has been developed. The reaction undergoes under the undivided electrolysis conditions and obviates the need for any catalysts and chemical oxidants....
