The reduction of ω-chloroperfluoroalkyl iodides(1a-b) with LiALH4 gave ω-chloroperfluoroalkyl hydride(3) and α,ω-dihydroperfluoroalkane(4). However, in the presence of olefin, the addition product (6) was obtained. The reaction can be partly suppressed by p-dinitrobenzene (p-DNB), and tetrahydrofuran derivatives were obtained from the reaction of ω-chloroperfluoroalkyl iodides with diallyl ether. A

Perfluoroalkyliodides reacted with alkenes in acetonitrile solution containing catalytic amounts of an organophosphine under mild conditions to give the corresponding adducts in moderate to high yields. Addition of hydroquinone to the reaction mixture suppressed the reaction. Diallyl ether reacted to afford tetrahydrofuran derivatives. These findings indicated that the reaction involved a free radical

Ceric sulfate, cerium(IV) ammonium nitrate, sodium persulfate, ammonium persulfate and potassium permanganate can smoothly induce the addition reaction of perfluoroalkyl halides (1) to electron-rich olefins (2) and alkynes (4) to give monoadducts (3 or 5). The perfluoroalkyl radical generated via possible pathways from 1 is discussed. (C) 1998 Elsevier Science S.A. All rights reserved.
