摘要：

The reaction of metallocene complexes of the type [eta(5):C5H4-(CH2)(n)-C6H5](2)MCl2 (n = 1-5; M = Zr, Hf) with EtLi gives the mono nuclear ethyl derivatives [eta(5):C5H4-(CH2)(n)-C6H5](2)M(Et)Cl and the metallacycles [eta(5):C5H4-(CH2)(n)-C6H5][eta(5):C5H4-(CH2)(n)- eta(1):C6H4]MEt. A large excess of EtLi affords the dinuclear species [eta(5):C5H4-(CH2)(n)-eta(6):C6H5](2)M2Cl2 (n = 2-5). All types of complexes can be activated with methylalumoxane (MAO) and then be used for catalytic polymerization of ethylene. (C) 2004 Elsevier B.V. All rights reserved.
