    • Process for preparing bridged, stereorigid, stereomerically pure dialkoxide metallocenes, diaryl oxide metallocenes and preferably diphenoxide metallocenes of the general formula Q(Cp)(Cp')M(OR 3 ) 2 in which Cp = a cyclopentadienyl, an indenyl or a fluorenyl radical, Cp' = one of the Cp groups, Q = a single- or multimembered bridge (R 1 -Z-R 2 ) b between Cp and Cp', in which R 1 and R 2 may be the same or different and are each a hydrogen atom, a C 1 -C 10 -alkyl group, a C 6 -C 10 -aryl group, and Z is carbon, silicon or germanium where b = 1, 2 or 3, M = a transition metal of group 4, especially Zr and Hf and Ti, O = oxygen, R 3 = a C 1 -C 10 -alkyl group, a C 6 -C 10 -aryl group, where the alkyl group may be branched or unbranched and may be substituted by aryl groups, and the aryl group may contain further substituents, which is characterized in that, in the first stage, a bridged, stereorigid metallocene dihalide in the form of a rac/meso mixture, having the general formula Q(Cp)(Cp')M(X) 2 is reacted with an alkylating reagent of the general formula R 4 -M-(X) n in which R 4 = a C 1 -C 10 -alkyl group, a C 6 -C 10 -aryl group, M = an alkali metal or alkaline earth metal, preferably Mg, Na or Li, X = halogen, especially Cl and Br, n = the oxidation number of M reduced by 1, and then the resulting reaction mixture or the intermediately isolated dialkylmetallocene is reacted with an alcohol, an aryl alcohol or a phenol of the general formula HO-R 3 in which HO = a hydroxyl group, R 3 = a C 1 -C 10 -alkyl group, a C 6 -C 10 -aryl group, where the alkyl group may be branched or unbranched and may be substituted by aryl groups, and the aryl group may contain further substituents.
