Fluoroalkyliodides react with alkenes in the presence of catalytic amounts of iron to give the corresponding adducts in good yields, the influence of solvent on the reaction is discussed and a SET initiated radical chain mechanism is proposed.

and the reaction could be inhibited by p-DNB. All these results seem to show that a radicalmechanism is involved in non-ethereal solvents. However, both radical addition and fluroalkyl Grignardreagent reactions are involved in THF. The formation of fluoroalkylmagnesium iodide is also found to proceed through a radical intermediate.

Addition of fluoroalkyliodides to alkenes can be catalysed by Raneynickel under mild conditions to give adducts in good yields; a single electron transfer initiated free radical chain mechanism is suggested.
The reaction of polyfluoroalkyl iodides with alkenes or 4-pentenoic acid promoted by sodium bisulfite or sodiumsulfite in DMF aqueous solution was realized. The reaction of alkenes gave corresponding adducts, while γ-lactones were obtained in the case of 4-pentenoic acid in good yields.

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
