Polyfluoroalkylation of octa-1,7-diene promoted by dichlorobis-(π-cyclopentadienyl)titanium and iron powder
Abstract
Per(poly)fluoroalkylation of octa-1,7-diene 1 with per(poly)fluoroalkyl iodides 2 or bromides 4, in the presence of catalytic amounts of dichlorobis(π-cyclopentadienyl)titanium(IV) and iron powder, provides 1:1 linear adducts 3, 5 and/or cyclic products 6 depending on the reactivity of the halides 2 and 4. A radical mechanism is proposed.
