HAT‐Promoted Electrochemical Amination: C(sp2)−H/N−H Cross Dehydrogenative Coupling

Abstract A direct amination of quinoxalin‐2(1 H )‐ones via electrochemical C( sp 2 )−H/N−H cross dehydrogenative coupling was established by using TMSN 3 as the hydrogen atom transfer (HAT) reagent. Remarkable features of this synthetic strategy include operational simplicity, transition metal‐ and chemical oxidant‐free conditions, and broad functional group tolerance. A wide range of primary, secondary amines and quinoxalinones are tolerated, giving the corresponding secondary and tertiary amination products in good to excellent yields. magnified image
