Photo‐Driven Direct C−H Arylation of Quinoxalin‐2(1H)‐Ones with Aryltriazenes under Catalyst‐Free and Ambient Conditions

A photo‐induced direct arylation of quinoxalin‐2(1H)‐ones with aryltriazenes under catalyst‐free and ambient conditions was developed. The synthetic importance of this methodology was showcased by the simple operation, good functional group tolerance, and gram‐scale synthesis. A photo‐promoted direct arylation of quinoxalin‐2(1H)‐ones with aryltriazenes under catalyst‐free and ambient conditions was developed. The synthetic importance of this methodology was showcased by the simple operation, good functional group tolerance, gram‐scale synthesis, and catalyst‐free conditions.
