Abstract

Green and efficient C-C bond cleavage/cyanoalkylation of quinoxalin-2(1 H)-ones and other heteroarenes under visible light or sunlight irradiation is described. The reaction proceeds under mild conditions at room temperature without transition-metal catalysts and extra bases. Notably, the products enable facile transformations to various significant organic compounds.
