We report the synthesis of α‐trifluoromethylacrylates from α‐trifluoroborylacrylates via a stereoretentive radical trifluoromethylation with inexpensive reagents NaSO2CF3 and TBHP at room temperature. Under these conditions, a wide substrate scope afforded the (E)‐diastereomer exclusively in moderate to good yield. The utility of the reaction products is demonstrated in the synthesis of phenyl‐4H‐pyran
