The addition of tetrachloromethane to trifluoroethene catalyzed by copper complexes gives 1:1 adducts in up to 97percent yield under mild reaction conditions.The catalytic activity and the regioselectivity of copper, ruthenium and palladium complexes and dibenzoyl peroxide have been compared.Differeneces in regioselectivity indicate that the copper-coordinated trichloromethyl radical is involved in copper-assisted addition reactions, whilst free-radical species in an uncomplexed form play a role in other cases.
