Both quinoxalin‐2(1 H )‐ones and nitriles are valuable organic compounds, and it is an interesting task to introduce cyano into quinoxalin‐2(1 H )‐ones. Herein a regioselective C−H cyanation of quinoxalin‐2(1 H )‐ones was developed with a nucleophilic cyano source TMSCN under electrochemical oxidative conditions. This process allowed the synthesis of C3 cyanated quinoxalin‐2(1 H )‐ones in moderate to excellent yields in the absence of transition‐metal catalysts and organic hydroperoxides.
