Electrochemical Oxidative C−H Cyanation of Quinoxalin‐2(1H)‐ones with TMSCN

Regioselective electrochemical C−H cyanation of quinoxalin‐2(1H)‐ones with a nucleophilic cyano source TMSCN was achieved using an undivided electrolytic cell. Transition metal‐ and organic hydroperoxides‐free conditions were the remarkable features of this protocol.
