metallacyclic zirconocene complexes. In this reaction aromatic CH bonds can be activated in unbridged and bridged metallocenedichloride complexes even if the corresponding phenyl ringscontain halogen substituents such as fluorine or chlorine. After the activation with methylalumoxane (MAO), all the metallocene complexes prove as attractive catalysts for ethylene polymerization reactions. Because of their Lewis
