Addition of 1,2-dihaloperfluoroalkanes to various alkenes promoted by catalytic amounts of dichlorobis(π-cyclopentadienyl)titanium(IV) Cp2TiCl2 and iron powder gives 1:1 adducts in excellent yields. The reaction is performed in protic solvent (EtOH) without dehalogenation. A radical chain mechanism initiated by dichlorobis(π-cyclopentadienyl)-titanium(III) Cp2Ti(III)Cl is proposed.
