undergo cyclometallation with [Pd(OAc)2]3 (in some cases the dimeric products 2 were isolated) and subsequently react with lithium chloride to give chloride complexes, which are dimeric 3a–c, or monomeric for the C3H6OH-functionalised complexes 4d,e which have a C,N,O tridentate imine. The chloride complexes subsequently react with triphenylphosphine, and in some cases pyridine, to give mononuclear complexes
