摘要： 将MeCpNdCl2·2LiC1·nTHF和2摩尔t-BuLi于四氢呋喃和戊烷混合溶剂中反应,合成得到一种新的阴离子型配合物〔Li(DME)3〕〔(η5－MeCp)Nd(t－Bu)3〕,用元素分析,红外光谱等作了表征,配合物溶于苯乙烯,可单独引发苯乙烯本体聚合,得无规聚苯乙烯。

Abstract: An anionic complex 〔Li(DME)3〕〔(η5－MeCp)Nd(t－Bu)3〕 was obtained by the reaction of MeCpNdCl2.2LiCl·nTHF with 2 mols of t-BuLi in the mixed soIution of THF and pentane. The complex was characterized by elemental analysis and IR spectroscopy. The complex is soluble in styrene and able to catalyze its polymerization in bulk to give an atactic polystyrene.

Key words: cyclopentadienyl rare earth complex, synthesis, styrene, catalytic polymerization
