Visible-light-initiated Cross-Dehydrogenative Coupling of Quinoxalin-2(1H)-ones and Simple Amides with Air as An Oxidant

By using ambient air as an oxidant, various N-acylated 3-aminoquinoxalin-2(1H)-ones were efficiently synthesized through visible-light-promoted Rhodamine B-catalyzed amidation reaction of quinoxalin-2(1H)-ones and amides under metal-free and strong oxidant-free conditions.
