A visible-light photoredox-catalyzed four-component reaction for the construction of sulfone-containing quinoxalin-2(1<i>H</i>)-ones

Abstract

A visible-light photoredox-catalyzed four component reaction of quinoxalin-2(1 H )-ones, alkenes, aryldiazonium, and sodium metabisulfite leading to sulfone-containing quinoxalin-2(1 H )-ones has been developed.
