Shigehisa, Hiroki published the artcileCobalt-Catalyzed Hydrofluorination of Unactivated Olefins: A Radical Approach of Fluorine Transfer, Recommanded Product: 3-Methylbut-2-en-1-yl benzoate, the publication is Organic Letters (2013), 15(20), 5158-5161, database is CAplus and MEDLINE.
Alkyl fluorides were prepared regioselectively in 41-82% yields by hydrofluorination of alkenes with 1-fluoro-2,4,6-trimethylpyridinium tetrafluoroborate and 1,1,3,3-tetramethyldisiloxane in the presence of a cobalt salen complex; the reactions occurred to give the Markovnikov regioisomers exclusively, tolerated acetal, ester, amide, tosylate, nitro, bromo, and thienyl moieties, and were performed (in three cases) on approx. 1 g scale in similar yields to those found on smaller scale. Reaction of a diallylsulfonamide yielded a fluoroalkylpyrrolidine, implying the generation of a radical intermediate in the hydrofluorination reaction.
