| 摘 要： | 研究发现Cp~2ZrL~2(L=Cl,Me,OC~6H~4-p-Me)/EAO(乙基铝氧烷)可同步催化乙烯齐聚-环化反应，不仅给出链状烯烃，而且生成环状剂聚物－－亚甲基环戊烷。环状齐聚物的选择性取决于主催化剂的结构和浓度，反应介质，预反应温度和反应温度，反应时间，Al/Zr比及烷基铝水解程度等因素，加入碱性第三组分对催化活性和选择性亦有一定影响。在优化反应条件下，亚甲基环戊烷的选择性达到37%。

| Abstract: | The oligomerization of ethylene catalyzed by Cp2ZrL2 (L = Cl, Me, OC6H4- p - Me)/EAO (ethylaluminoxane) afforded not only common chain oligomers but also methylenecyclopentane. It is the first example of oligomerization and simultaneous cyclization of ethylene to a cyclic oligomer. The selectivity of methylenecyclopentane, affected by the structure and the concentration of precatalysts, solvents, aging and reaction temperature and some other factors, came up to 37% when a third - component C5H5N was added to the Cp2ZrCl2/EAO system under optimal conditions. |
