Visible-light-promoted C3-H alkoxycarbonylation of quinoxalin-2(1H)-ones or coumarins with alkyloxalyl chlorides Herein, we describe a green and efficient photoredox catalytic C3-H alkoxycarbonylation between quinoxalin-2(1H)-ones or coumarins and readily available alkyloxalyl chlorides under ambient conditions. A series of quinoxaline-3-carbonyl and coumarin-3-carbonyl compounds are prepared through the radical addition of the in situ-generated alkoxycarbonyl radicals.
