已知中性芳烃过渡金属有机配合物是一类重要的配合物,它不仅可催化芳烃取代反应,而且还可以和烷基铝组成催化剂催化烯烃聚合、齐聚合,对于稀土的这类有机配合物的合成和结构的研究仅在1986年才开始,Cotton报道了第一个配合物Sm(C_6Me_6)(AlCl_4)_3的结构,而后,我们也报道了一系列的中性芳烃稀土有机配合物的合成及晶体结构,但对于这 It is known that the neutral aromatic transition metal organic complex is an important kind of complex, which not only can catalyze the aromatic substitution reactions but also can catalyze the polymerization and oligomerization of olefins with the aluminum alkyl catalyst. For such rare earth organic complexes The synthesis and structure of the complex have only been started in 1986. Cotton reported the structure of the first complex, Sm (C_6Me_6) (AlCl_4) _3, and then we reported the synthesis of a series of neutral aromatic rare earth organic complexes And the crystal structure, but for this
