Cross-Dehydrogenative Coupling Reaction and Arylation of Quinoxalin-2(1H)-ones under Iodide/Peroxide Conditions

Cross-Dehydrogenative Coupling Reaction and Arylation of Quinoxalin-2(1H)-ones under Iodide/Peroxide Conditions

A simple method has been developed for the synthesis of ­3-(2-oxo-2-phenylethylidene)-3,4-dihydroquinoxalin-2(1H)-one and ­3-aryl-quinoxalin-2(1H)-one derivatives through C–H activation of quinoxalin-2(1H)-ones by peroxides and iodide. In this protocol, the per­oxide (TBPB) serves as both the radica...
