are capable of converting O‐based electrophiles into trifluoromethanes. The copper‐mediated trifluoromethylation of benzylicxanthates using Umemoto’s reagent as the source of CF3 to form CCF3 bonds is described. The method is compatible with an array of benzylicxanthates bearing useful functional groups. A preliminary mechanistic investigation suggests that the CCF3 bond forms by reaction of the
