摘要
Using visible light as energy to form free radicals has important synthetic value.A novel and efficient visible-lightmediated strategy has been developed for the generation of thiobenzene radicals through cerium-catalyzed activation of the disulfides.Through this photochemical reaction,various 3-sulfenylated quinoxalin-2(1H)-ones can be conveniently obtained in good yields with good functional group tolerance.Our transformation provides an alternative that allows rapid access to various C3 sulfenylated quinoxalin-2(1H)-ones in a sustainable and practical manner.
