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.
