Abstract

The semi-heterogeneous g-C₃N₄/NaI dual catalytic system-driven C–C bond formation between quinoxalin-2(1H)-ones and arylhydrazines under blue light irradiation has been reported for the first time. The photo-generated hole acted as a traceless oxidant to turn over the iodide salt redox catalyst cycle and the photo-generated electron served as a clean reductant to promote the bond formation process. A wide range of 3-arylquinoxaline-2 (1H)-ones were obtained in high yields with excellent functional group tolerance.
