Formation, Reactivity, and Properties of Nondative Late Transition Metal−Oxygen and −Nitrogen Bonds

摘要: Complexes containing bonds between heteroatoms such as nitrogen and oxygen "late" transition metals (i.e., those located on the right side of series) have been implicated reactive intermediates in numerous important catalytic systems. Despite this, Our understanding M-X linkages still lags behind that their M-H M-C analogues. New synthetic strategies now made possible isolation study a variety monomeric late-metal alkoxide, aryloxide, amide complexes, including parent hydroxide species. The these materials form surprisingly strong to metal centers, bond energies do not necessarily correlate with corresponding H-X bonds. complexes typically exhibit nucleophilic reactivity, some cases hydrogen proton donors, even deprotonate relatively weak acids. These observations, well thermodynamic investigations, suggest late - heteroatom are strongly polarized possess significant ionic character, properties play an role interactions organic compounds.
