摘要

Is reacted with an alkaline earth metal compound or alkali metal compound of the transition metal-aromatic complexes of the non-crosslinked or crosslinked, heated to a temperature of -78~250 ℃ reaction mixture obtained, the present invention is the reaction product and characterized by producing a partially hydrogenated metallocene or the corresponding hydrogenated by the at least partially hydrogenated in the presence of a suitable catalyst, ansa hydrogenated racemic or in a partially hydrogenated - process for preparing metallocene complexes, and to a method as a catalyst component or catalyst for the polymerization of olefinically unsaturated compounds or as reagents or catalysts in stereoselective synthesis, using the above complex.
