A mild and efficient method for the arylation of quinoxalinones are described using aryldiazonium tetrafluoroborates as aryl source. Reactions proceeds at room temperature in a short reaction time of 1 h without metal catalysts and bases. Broad functional group tolerance was observed with good yield...
