Description
Summary:[Display omitted] •Hotocatalytic arylation.•H2O as green solvent.•39 examples with moderate-to-good yields. An efficient visible-light-induced CH arylation of quinoxalin-2(1H)-ones in H2O is developed, which has the advantages of mild reaction conditions, environmental friendliness and good functional group tolerance. This strategy provides a simple operation method to access various 3-aryl quinoxalin-2(1H)-ones in moderate to good yields.
