Fluorinated radicals were generated from RfSO2Cl by photoredox catalysis under mild conditions, where Rf = n-C4F9, CF3, CF2H, CH2F, CH2CF3, and CF2CO2Me. This method provided a general way to construct fluorinated 2-oxindoles from reaction with N-arylacrylamides via a proposed tandem radical cyclization process.

The redox-neutral tetrafluoroethylation of alkynes with 1,1,2,2-tetrafluroroethanesulfonic acid (TFESA) and azobis(isobutyronitrile) (AIBN) proceeds via the formation of vinyl tetrafluoroethanesulfonates followed by a radical tetrafluoroethylation. Experimental and theoretical results support an intermolecular reaction.
