The development of efficient methods for accessing fluo­rinated functional groups is desirable. Herein, we report a two-step method that utilizes catalytic copper for the decarboxylative trifluoromethylation of propargyl bromodifluoroacetates is described. This protocol affords a mixture of propargyl trifluoromethanes and trifluoromethyl allenes.
