三核过渡金属配合物在催化反应中的研究进展

Polynuclear transition metal complexes are widely used as homogeneous catalysts, and the polymetallic active sites of enzymes also play an important role in the mechanism of biochemical reactions under ambient conditions. As the efficient polymetallic catalysts for the activation of small molecules, trinuclear metal complexes have been attracted extensive attention. In order to understand the role of trinuclear transition metal complexes in catalytic reactions, we have classified the trinuclear transition metal complexes according to metal centers, and summarized the characteristics of their ligands, as well as their catalytic applications. Based on the metal centers, the geometric structure and electronic characteristics of the complexes are discussed. Based on the peripheral ligands, the characteristics of the coordination environment, which enable the aggregation of three independent metal sites, are highlighted. In terms of catalytic applications of trinuclear transition metal complexes, the catalytic mechanisms involving specific chemical bonds activation are focused on. Finally, we outlook the crucial potential application in this emerging field.
