Metal‐Free Direct C3−H Alkylation and Arylation of Quinoxalin‐2(1H)‐Ones with Inert Alkyl and Aryl Chlorides

Abstract In the present manuscript, we reported the first visible‐light‐enabled direct C3−H alkylation/arylation of quinoxalin‐2(1 H )‐ones with unactivated alkyl/aryl chlorides under metal‐free conditions. A wide range of unactivated alkyl and aryl chlorides containing different functionalities are coupled with a variety of quinoxalin‐2(1 H )‐one derivatives under mild reaction conditions to afford the C3‐alkyl/aryl substituted quinoxalin‐2(1 H )‐ones in moderate to good yields.
