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 designed mechanistic studies including the radical detection by EPR. 2012 Elsevier Science.

A certain number of isomeric 2-phenylquinoxalines N-oxides bearing substituents at position 6/7 were prepared in order to investigate anti-microbial activity. The effect of some electron-withdrawing groups seem to increase an anti-Trichomonas vaginalis ac
