Electrochemical Oxidative C–H Arylation of Quinoxalin(on)es with Arylhydrazine Hydrochlorides under Mild Conditions

Abstract

A practical and scalable protocol for electrochemical arylation of quinoxalin­(on)­es with arylhydrazine hydrochlorides under mild conditions has been developed. This method exhibits high efficiency, easy scalability, and broad functional group tolerance. Various quinoxalin­(on)­es and arylhydrazines underwent this transformation smoothly in an undivided cell, providing the corresponding aryl-substituted quinoxalin­(on)­es in moderate to good yields. A radical mechanism is involved in this arylation reaction
