Visible-light induced three-component alkynyl-difluoroalkylation of unactivated alkenes

A visible-light induced three-component reaction of difluoroalkyl halides, unactivated alkenes, and alkynyl sulfones is described, providing a direct and general approach to the construction of synthetically valuable β-difluoroalkylated alkynes under room temperature conditions. This represents the...

Zusammenfassung:	A visible-light induced three-component reaction of difluoroalkyl halides, unactivated alkenes, and alkynyl sulfones is described, providing a direct and general approach to the construction of synthetically valuable β-difluoroalkylated alkynes under room temperature conditions. This represents the first intermolecular alkynyl-difluoroalkylation of unactivated alkenes.
