【摘要】通过（CF₃COO）₂NdCl·EtOH和AlEt₃的反应合成了一种新的双金属稀土络合物。这一络合物是（CF₃COO）₂NdCl·EtOH-AlEt₃均相催化体系的活性体,并提出了活性是通过β消除反应生成稀土双金属桥键络合物的设想。更多还原

【Abstract】 A new bimetallic crystalline lanthanide complex which is active for polymerization of dienes was isolated from the homogeneous solution prepared by the reaction of (CF3COO)2NdCl·EtOH with Et3Al.A bridged structure of the lanthanide complex was proposed.更多还原
