Fluoroalkyl iodides reacted with alkenes in the presence of hydridocarbonyltris(tri-phenylphosphine)iridium (I) to give the corresponding adducts in excellent yields under the mildconditions.Fluoroalkyl iodides reacted also with alkynes to afford E isomer of adducts predomi-nantly.Addition of free radical inhibitor or single electron transfer scavenger to the reaction mix-ture partially suppressed the reaction.Diallyl ether could trap the fluoroalkyl radical to affordtetrahydrofuran derivative.XPS showed that the valence of Ir (I) rised at the end of the reaction.All findings seem to indicate that the reaction involves a free radical chain mechanism initiated byIr (I).
