制备了具有两个亚氨基吡咯基配体 Zr(Net2)2(pyr)2 (2a–e)（pyr = 2-(N-芳基亚氨基甲基)吡咯基）和 ZrCl2(pyr)2 (3a–e) 的二酰氨基和二氯锆配合物。基于核磁共振波谱以及配合物 3a 的晶体学研究，阐明了二酰氨基和二氯部分的顺式构型。我们证明这些锆配合物成为在过量甲基铝氧烷存在下乙烯聚合的催化剂前体。
Diamido and dichloro zirconium complexes having two iminopyrrolyl ligands, Zr(Net2)2(pyr)2 (2a–e) (pyr = 2-(N-aryliminomethyl)pyrrolyl) and ZrCl2(pyr)2 (3a–e), were prepared. The cis-configuration of diamido and dichloro moieties was elucidated on the basis of NMR spectroscopy as well as by a crystallographic study for complex 3a. We demonstrated that these zirconium complexes became catalyst precursors for the polymerization of ethylene in the presence of excess amounts of methylaluminoxane.
