【Abstract】 The research status of synthesis and characterization and the application of lanthanide borohydride complexes were reviewed.Lanthanide borohydride complexes were used in organic synthesis with structural diversity and high catalytic activity.Not only lactone,lactide and methyl methacrylate but also single and double olefins were polymerized respectively with catalysts of Lanthanide borohydride complexes.Especially lanthanide borohydride complexes with large groups as skeleton were used as organic polymerization catalysts.The ligand skeleton with the multidentate mode usually coordinated with the lanthanide metal center,and its varied stereostructure had great influence on the properties of the lanthanide borohydrides and had the higher catalytic activity for initiating the polymerization of different monomers.The catalysts were favorable to control the molecular weight and distribution of polymer.They were effective catalysts for the synthesis of highly stereoselective polymers and the modification of functional materials.The catalytic performance of lanthanide borohydride complexes in the polymerization was detailed,and its application prospect in organic synthesis in the future was prospected.更多还原
