Abstract

Reported herein is an efficient α-arylation of α-fluoro-α-nitro­sulfonylmethanes using diaryliodonium salts. A wide range of α-fluoronitrosulfonylmethane substrates underwent α-arylation smoothly to produce the corresponding adducts bearing a fully substituted fluorocarbon center in good to excellent yields. The protocol was subsequently shown viable for the α-arylation of α-cyano-α-fluorosulfonylmethane derivatives yielding highly valuable cyano building blocks.
