Abstract
The visible‐light‐promoted difluoromethylation and trifluoromethylation/cyclization of β, γ‐unsaturated oximes has been successfully accomplished with fluorinated sulfones as the difluoromethylation and trifluoromethylation reagents. The reaction was proposed to proceed through a sequence comprising CF2X‐radical generation, fluoromethyl radical addition, single electron oxidation, and intramolecular cyclization to afford the corresponding di and trifluoromethylated isoxazoline derivatives in an overall redox‐neutral process.
