Copper-Catalyzed Decarboxylative Trifluoromethylation of Propargyl Bromodifluoroacetates.

The development of efficient methods for accessing fluorinated functional groups is desirable. Herein, we report a twostep 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. [ABSTRACT FROM AUTHOR]
