Dendritic metal catalysts are prepared by loading metal active centers on dendritic macro molecules. They not only have the unique structure of dendritic macro molecules but also have the functional properties of metal complexes, combining the features of both homogeneous and heterogeneous catalytic systems. In catalytic reactions, they have a synergistic effect, showing high catalytic activity and good stability. This paper first introduces the development and types of dendritic large molecules, then focuses on reviewing the research progress of dendritic metal catalysts in various catalytic reaction types (Kharasch addition, Diels-Alder, Stille reaction, allylic alkylation, hydrogenation of olefins, copolymerization of olefins, Knoevenagel condensation, Michael addition, polymerization of olefins), explaining the reasons for various dendritic effects, and discussing the future development directions of dendritic metal catalysts.
