“Sandwich” diimine-copper (I) complex catalyzes reactions of CF3CHN2 and CF3CF2CHN2 reagents with C(sp3)−H bonds in a large panel of alkyl esters, halides, and protected amines resulting in introduction of trifluoroethyl- and pentafluoropropyl groups with predictable regioselectivities. Identical C−H functionalization conditions and stoichiometries are employed for generality and synthetic convenience
