Photoredox Radical‐Polar Crossover Reaction ofgem‐Difluoroalkenes: A Facile Access to Diverse Difluoroalkyl Sulfides

Abstract

Difluoroalkyl sulfide (‐CF2S‐) moieties are an important class of skeletons in medicinal chemistry. Herein, a photoredox radical‐polar crossover reaction is reported for the three‐component thiofluorination, thiohydroxylation, thioalkoxylation, thioaminolation, and thiochlorination of gem‐difluoroalkenes towards diverse α‐functionalized difluoroalkyl sulfides. Such an approach features mild conditions, operational simplicity, and good substrate scope.
