Abstract

The reaction of phenylalkyl substituted zirconocenedichloride complexes with two equivalents of n-butyllithium gives metallacyclic zirconocene complexes. In this reaction aromatic CH bonds can be activated in unbridged and bridged metallocenedichloride complexes even if the corresponding phenyl rings contain halogen substituents such as fluorine or chlorine. After the activation with methylalumoxane (MAO), all the metallocene ...
