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. (Figure presented.).
