Abstract
AbstractHerein, we report the α−C−H acyloxylation of sulfides and disulfides enabled by hypervalent iodine(III) reagents via photoredox catalysis. The methoxylbenziodoxole derivatives serve as the hydrogen atom transfer agent, the mild oxidant, and the acyloxylation source in the reaction. External nucleophiles can also be introduced to the α−C−H of sulfides. The reaction applies to various aryl and alkyl sulfides including methionine peptide derivatives. Disulfides are applicable for the first time with excellent chemoselectivity and functional group compatibility.
