The reaction of metallocene complexes of the type [η5:C 5H4-(CH2)n-C6H 5]2MCl2 (n=1-5; M=Zr, Hf) with EtLi gives the mono nuclear ethyl derivatives [η5:C5H 4-(CH2)n-C6H5] 2M(Et)Cl and the metallacycles [η5:C5H 4-(CH2)n-C6H5] [η5:C5H4-(CH2) n-η1:C6H4]MEt. A large excess of EtLi affords the dinuclear species [η5:C5H 4-(CH2)n-η6:C6H 5]2M2Cl2 (n=2-5). All types of complexes can be activated with methylalumoxane (MAO) and then be used for catalytic polymerization of ethylene.
