The cyclometallated Pd compound PdCl[PPh2CH2CH2CH-(cyclic)CH2CH2PPh2]1, obtained from PdCl2(Ph2P(CH2)5PPh2) in refluxing DMF (N,N-dimethylformamide), was characterized by NMR and X-ray single-crystal diffraction analysis. The cyclometallation of MCl2(Ph2P(CH2)5PPh2) (M = Pd, Pt) to give 1 and its Pt(II) analogue was probed using electrospray ionisation mass spectrometry (ESMS). The reactivity of 1 towards neutral ligands such asphosphines and pyridines as well as basic metal complexes such as pyrid ine-thiolate compounds of Au(I), Hg(II) and Pt(II) in solution was also investigated. The results showed that the chloride trans to the Pd-C bond is susceptible to ligand replacement. A number of entry metalloligandswas examined in an attempt to establish a route to cyclometallated aggr egates and clusters.
