Photoredox-catalyzed sulfonylation of difluoroenoxysilanes with the insertion of sulfur dioxide

A photoredox-catalyzed three-component reaction of aryldiazonium tetrafluoroborates with sodium metabisulfite and 2,2-difluoro enol silyl ethers is described. By using sodium metabisulfite as the source of sulfur dioxide, this method provides an elegant access to α,α-difluoro-β-ketosulfones in moder...
