The method enables the synthesis of gem-difluorinated sulfonyl-1,4-dienes using alkynes and trifluoromethyl alkenes.
This reaction employs selective C-F bond activation, achieving a high stereospecificity.
Metal-free conditions enhance the reaction efficiency, appealing for greener chemistry approaches.
Using sodium sulfinates in this process demonstrates a novel three-component coupling strategy.

Implication

Photocatalyzed allylsulfonylation generates gem-difluorinated compounds in alkynes, indicating an efficient synthesis method.

Abstract

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...
