= PPh3(4f)]. An X-ray analysis of cis-[PdCl2(PPh3)(Me2SNC4H3N2)]·CH2Cl2(4f) revealed that the pyrimidine rather than the sulphimide N atom is the point of attachment of the sulphimide ligand to Pd. Conformational energy calculations suggest that electronic rather than steric factors determine which N atom acts as donor to Pd.
