2,3-Diarylquinoxaline directed mono ortho-aroylation protocol has been developed using aromatic aldehydes or alkybenzenes as aroyl surrogates. Out of the four available ortho sp2 C-H bonds in the two aryl rings of 2,3-diarylquinoxaline one of the C-H bond is selectively ortho-aroylated. The reaction proceeds via the aroyl radical path in the case of aromatic aldehydes while the alkylbenzenes follow either an aroyl radical or a benzyl radical path. Varieties of functional groups present as substituents in 2,3- diarylquinoxalines, aromatic aldehydes and alkylbenzenes are tolerated under the present reaction conditions.
