Visible-light-promoted direct C–H/S–H cross-coupling of quinoxalin-2(1<i>H</i>)-ones with thiols leading to 3-sulfenylated quinoxalin-2(1<i>H</i>)-ones in air

Abstract

A new and efficient visible-light-mediated strategy has been developed for the synthesis of 3-sulfenylated quinoxalin-2(1<italic>H</italic>)-ones <italic>via</italic> rhodamine B catalyzed C–H/S–H cross-coupling of quinoxalin-2(1<italic>H</italic>)-ones with thiols in air at room temperature.
