摘要

A novel Et3N-catalyzed oxidative dehydrogenative coupling of α-unsubstituted carbonyl compounds with aryl diamines leading to quinoxaline derivatives using molecular oxygen as oxidant has been developed. Six hydrogen dissociations involving 2 sp3 C–H bonds activation are realized under mild conditions in this approach. Plausible mechanism is proposed for this novel Et3N-catalyzed transformation on the basis of the aboratively ...
