摘要

Trifluoromethylation of propargylic alcohols to provide (Z)-α-trifluoromethylated enones and β-unsubstituted a-trifluoromethylated enones proceeded with high yield and selectivity in the presence of CuI/Re_2O_7. The Z isomer was formed under kinetic control, though it is less stable than the E isomer in terms of steric repulsion.
