    本发明公开一种含杂环结构的桥联茂金属化合物及其制备方法和应用,该化合物具有反式结构式(I)或顺式结构式(Ⅱ):其中,M是Ti、Zr或Hf,A是S或O;Y是C或Si;R1和R2是1‑6个碳数的烷基或芳基,彼此相同或不同;X1和X2各自独立地为与M形成σ‑键的配体。该桥联茂金属化合物与助催化剂配合,适用于α‑烯烃均聚和共聚,特别适用于长链α‑烯烃的共聚合,如乙烯与辛烯的共聚。本发明所涉及的双茂桥联类茂金属催化剂,其中含杂原子配体被结合到过渡金属上,金属上下两个茂杂环结构不尽相同,这种特殊的对称性结构,可以用于α‑烯烃均聚和共聚合,且使得长链α‑烯烃插入率较高。

    (11), 1,2-dimethyl-3H-cyclopenta[b][1]benzothiophene (14). After a deprotonation of 2, 4, 11, and 14 with n-BuLi, followed by treatment of the resulting lithium salts with (η5-C5Me5)ZrCl3, complexes (η5-Cp‘)(η5-C5Me5)ZrCl2 were obtained. The ligand 6 gave a mixture of undesirable products instead of the respective metallocene. Two of them were isolated and turned out to be the polynuclear hydride complex
