| Abstract: | A visible light photoredox-catalyzed C-3 phosphorylation of quinoxalin-2(1H)-ones with diphenylphosphine oxide has been developed. The reaction was effectively accelerated using an inexpensive eosin B as a photoredox catalyst under ambient air at room temperature without any other metal, oxidant, or additive. This approach offers a facile way to prepare 3-diphenylphosphorylated quinoxalin-2(1H)-one derivatives. |
