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

Abstract 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. magnified image
