摘　　要：用1, 2 -二茚基乙烷[ (CH2 )2 (C9H7 )2 ]与四配位的三[三甲基硅基胺基]镱的络合物{ [ (Me3Si)2N]3Yb(Ⅲ) (μ- Cl)Li(THF)3 }反应,生成桥联二茚基镱的胺基配合物[ (CH2 )2 (C9H6 )2YbN(SiMe3 )2 ],其结构经1HNMR, IR, XRD, GPC和元素分析表征,并初步研究了其对甲基丙烯酸甲酯聚合反应的催化活性。1-2-Bis(indenyl)ethane-derived ytterbium amides[(CH_ 2)_ 2(C_ 9H_ 6)_ 2YbN(SiMe_ 3)_ 2] was synthesized by the reaction of 1,2-bis(indenyl)ethane with[(Me_ 3Si)_ 2N]_ 3Yb(Ⅲ)(μ-Cl)Li(THF)_ 3 in toluene. The complex was characterized by 1H NMR, IR, XRD, GPC and elemental analysis. Its catalytic activity was also studied in polymerization of MMA.
