The present invention relates to a specific process for the diastereoselective synthesis of racy diorganosilylbis(2methylbenzo[e]indenyl)zirconium compounds of the formula I, by reacting the silyl-bridged bisindenyl ligand with a dihalozirconiumbis(3,5-di-tert-butylphenoxide)- base adduct to form the diorganosilylbis(2-methylbenzo[e]indenyl)zirconium bis(3,5-di-tert-butylphenoxide) and subsequently replacing the phenoxide groups by X using suitable replacement reagents to give the compound of the formula (I); where the substituents X can be identical or different and are each F, CI, Br, I or linear, cyclic or branched C1-10-alkyl; and the substituents R can be identical or different and are each linear, cyclic or branched C1-10-alkyl or C6-10-aryl; and also to the use of these compounds as catalysts.
本发明涉及一种特定的过程,用于选择性合成式I的立体异构二有机硅基双(2-甲基苯并[e]吲哚)锆化合物,其中通过将硅桥联双吲哚配体与二卤化锆双(3,5-二叔丁基苯氧)-碱加合物反应,形成二有机硅基双(2-甲基苯并[e]吲哚)锆双(3,5-二叔丁基苯氧),然后使用适当的置换试剂将苯氧基取代为X,以得到式(I)的化合物;其中取代基X可以相同或不同,且均为F、CI、Br、I或直链、环状或支链状的C1-10烷基;取代基R可以相同或不同,且均为直链、环状或支链状的C1-10烷基或C6-10芳基;同时还涉及将这些化合物用作催化剂的用途。
