A mild and direct C–H arylation of quinoxazolin-2(1H)-ones with aryldiazonium salts has been developed. A wide variety of 3-arylquinoxazolin-2(1H)-ones were synthesized in up to 92% yield at room temperature under metal-free conditions. This strategy tolerates a wide range of functional groups and shows environmental friendliness and practicality.
