Visible‐light‐induced Catalyzed Dehydrogenative Coupling of Quinoxalin‐2(1H)‐ones with Azoles Using Carbon Nitride

Abstract An efficient visible‐light‐induced catalyzed dehydrogenation coupling of quinoxalin‐2(1 H )‐ones with azoles was developed, a protocol that did not require prefunctionalization of the substrates and produced hydrogen (H 2 ). Meanwhile, this reaction proceeded without the addition of other metal and oxidant and provided a broad range of 3‐aminoquinoxalin‐2(1 H )‐ones in medium to good yield. Furthermore, this protocol provided advantages of easy and simple operation, high chemoselectivity, and a recyclable catalyst. A preliminary mechanistic investigation revealed that the reaction involved a radical process.
