Copper-mediated trifluoromethylation of allylic chlorides and trifluoroacetates was performed using a convenient Cu–CF3 reagent. The reaction is suitable for selective synthesis of allyl trifluoromethyl species. Mechanistic studies indicate that the reaction proceeds via a nucleophilic substitution mechanism involving allyl copper intermediates. The analogous Cu–F reagent was suitable for fluorination
