2-Benzoyloxy-F-propene, an F-enol ester, is shown to serve as a good and selective acceptor towards nucleophilic radicals generated from cyclic ethers, alcohols, and alkyl iodides to afford the addition product. The scope and synthetic utility of the radical addition reaction are described.
trifluorovinyl sulfide was prepared from the reaction of trifluorovinyllithium and S-phenyl benzenethiosulfonate. The fluorinated olefin showed reactivity with alkyl radicals generated from halogen-abstraction from alkyl halides. Reactions with alkyl halides required tris(trimethylsilyl)silane as a chain transfer reagent to improve selectivity of the products. Initiation of radical reaction was effected
