An efficient copper-catalyzed trifluoromethylation of polysubstituted alkenes assisted by decarboxylation of β,γ-unsaturated carboxylic acids has been achieved. The reaction provides a general method to construct allylic and vinylic CF3-substituted compounds under mild conditions.

Not one but two! A new strategy for the regiospecific construction of compounds with allylic CF2H groups has been developed. The decarboxylative (phenylsulfonyl)difluoromethylation of β,γ‐unsaturated carboxylic acids is catalyzed by a Lewis acid (CuCl2⋅2 H2O), and the resulting product easily undergoes desulfonylation.
