Visible-Light-Initiated Cross-Dehydrogenative Coupling of Quinoxalin-2(1<i>H</i>)-ones and Simple Amides with Air as an Oxidant

Abstract

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.
