Branched allylic CF3 products are accessible by copper‐catalyzed trifluoromethylation of allylsilanes with the Togni reagent I. The silyl group is critical to control the outcome of this reaction because in its absence, a product of addition between the alkene and the Togni reagent is formed preferentially. The reaction is inhibited with 2,2,6,6‐tetramethyl‐1‐piperidinyloxy (TEMPO) and is likely to

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.
