C6H4CH3-4, C6H4Cl-4) have been synthesized and characterized by elemental analyses and nuclear magnetic resonance (1H, 13C and 31P) spectroscopy. The methylpalladium complexes exist either as cis isomers or as a mixture of cis and trans forms, with the former predominating. The allylpalladium complexes exist in syn and anti forms. The dynamic behaviour in these complexes was studied by variable-temperature
