ω-phenylalkyl substituted ansa half-sandwich dichloride complexes of titanium and zirconium is described. These complexes react with butyllithium to give metallacycles via a CH activation reaction on the ortho position of the phenyl group. All complexes were used as catalyst precursors for homogeneous ethylene polymerization. The effect of the catalyst structure on the polyethylene properties is discussed.
描述了钛和锆的ω-苯基烷基取代的ansa半夹心二氯化物络合物的制备和表征。这些络合物与丁基锂反应,通过在苯基邻位的CH活化反应生成金属环。所有的络合物均用作均相乙烯聚合的催化剂前体。讨论了催化剂结构对聚乙烯性能的影响。
