= CF3 or CF2CF3) coupling at Pd complexes of general structure (PtBu3)PdII(Ph)(RF). The CF3 analogue participates in fast Ph-CF3 coupling (<5 min at 80 °C). However, the formation of side products limits the yield of this transformation as well as its translation to catalysis. DFT and experimental studies suggest that the side products derivefrom facile α-fluoride elimination at the 3-coordinate PdII

Complexed and reversibly activated arenes selectively react with a perfluoroalkyl anion under mild conditions, forming cyclohexadienyl adducts that readily undergo oxidation to perfluoroalkyl arenes.
