Addition of various polyfluoroalkyl halides including 1,2‐dihalopolyfluoroalkanes to 1‐octene is effected by using a catalytic amount of Cp 2 TiCl 3 (IV) and iron powder to give 1:1 adducts in excellent yields. The reaction is performed in EtOH or THF. A Cp 2 TiCl(III) mediated radical mechanism is proposed. Radical reactivity of polyfluoroalkanes toward 1‐octene was found to be ‐CF 2 I>‐CF 2 Br>‐CF 2 CCl 2 .
