C−H trifluoromethylation of quinoxalin‐2(1H)‐ones with commercially available sodium trifluoromethanesulfinate (CF3SO2Na) under visible light irradiation without any external photocatalyst has been developed, providing a variety of 3‐trifluoromethylquinoxalin‐2(1H)‐ones in moderate to excellent yield. Mechanistic studies have shown that1O2coexists with O2.−through the energy transfer and single‐electron transfer processes during the photoredox reaction.
