title: Photoredox-catalyzed tandem radical cyclization of N-arylacrylamides: general methods to construct fluorinated 3,3-disubstituted 2-oxindoles using fluoroalkylsulfonyl chlorides.
abstract: 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.
