Transmetalation: a new route to heteropolymetallic molecules and materials

Abstract The newly discovered transmetalation of polymetallic molecules by mononuclear transmetalators is an excellent source of a wide variety of related heteropolyatomic molecules and materials that cannot be obtained by other means. The systems discussed involve easily obtained reactants, stoichiometric reactions and easily separated products. Among the factors that affect specific transmetalation patterns are target structure, transmetalator identity and relative stability, redox phenomena, intramolecular ligand transfer and specific types of primary product fragmentation. A feature of reported transmetalation systems that make them excellent candidates for the production of new materials is that they are stoichiometric and flexible. Prospects for extending known systems to new targets and elements are discussed.
