【摘要】 综述了稀土硼氢化合物的合成、表征及其应用研究现状,稀土硼氢化合物用于有机合成具有结构多样性和高催化活性,不仅作为内酯、丙交酯和甲基丙烯酸甲酯聚合反应催化剂,还可以催化单、双组分烯烃聚合反应,特别是以大基团作为骨架的稀土硼氢化合物作为有机聚合反应催化剂,配体骨架通常以多齿模式与稀土金属中心配位,其多变的空间立体结构对稀土硼氢化合物的性能产生很大的影响,引发不同单体聚合具有较高的催化活性,有利于对聚合物分子量及分布控制,为合成高度立体选择性聚合物及对功能材料的改性提供了非常有效的催化剂,阐述了稀土硼氢化合物对聚合反应催化性能,并对其在有机合成应用前景进行了展望。

【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.
