RACEMOSELECTIVE SYNTHESIS OF RAC-DIORGANOSILYLBIS(2-METHYLBENZO[E]INDEYL) ZIRCONIUM COMPONDS

The present invention relates to a specific process for the diastereoselective synthesis of racy diorganosilylbis(2-methylbenzo[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.
