Abstract A copper-catalyzed α-selective C–H trifluoromethylation of acrylamides with TMSCF3 is described. A wide range of arenes and heteroarenes at the β-position of acrylamides are compatible with the reaction, affording the corresponding (E)-trifluoromethylated products in moderate to good yields. The reaction proceeded fast and can be completed within 30 min.
