| abstract | The present invention refers to a process for overcoming the problem of formation of oligomeric-polymeric complexes during preparation of cyclopentadienyl metallocenes comprising ligands bridged by at least three carbon atoms. According to the invention a process is presented comprising the steps of deprotonating a biscyclopentadienyl ligand bridged by a chain having a backbone of at least three carbon atoms by a base and reacting the deprotonated ligand with at least one alkali or alkaline earth metal alkylating agent and a salt of a transition metal belonging to group 3, 4, 5, 6 or to the lanthanide or actinide groups of the Periodic Table of the Elements. |
