The ability of bipyridyl-derived ligands to control the regioselectivity of Cu-catalyzed nucleophilic trifluoromethylation reactions of propargyl electrophiles provides various di-, tri-, and tetrasubstituted (trifluoromethyl)allenes, which can be further modified to generate complex fluorinated substructures.
