二价钐、镱有机配合物是一类强还原剂,它们不仅可以作为单电子转移试剂与R—X如卤代烃、醛、酮、不饱和烃及伯氢化物等富电子试剂反应,而且还可以催化炔烃氢化、乙烯聚合及甲基丙烯酸甲酯聚合。二价稀土有机配合物的合成、结构及催化性能的研究在近几年已越来越多地引起人们的重视,但二价烯土有机配合物催化苯乙烯聚合以及不同配体对催化 Bivalent samarium and ytterbium organic complexes are a class of strong reducing agents that not only can react with electron-rich reagents like R-X such as halogenated hydrocarbons, aldehydes, ketones, unsaturated hydrocarbons and primary hydride as single electron transfer reagents, but also It can also catalyze the alkyne hydrogenation, ethylene polymerization and methyl methacrylate polymerization. In recent years, more and more attention has been paid to the synthesis, structure and catalytic properties of divalent rare earth organic complexes. However, the bivalent organo-organic complexes catalyze the polymerization of styrene and the catalytic activities of different ligands
