Photocatalyzed Defluorinative Allylsulfonylation of Alkynes to Access gem-Difluorinated Sulfonyl-1,4-Dienes

A photocatalyzed three-component gem-difluoroallylsulfonylation of alkynes with trifluoromethyl alkenes and sodium sulfinates via selective C-F bond activation has been described. This metal-free allylsulfonylation provides an efficient strategy for the stereospecific...
