Abstract
Donor substituted carbon- and silicon-bridged zirconocene dichlorides of th e type [eta (5)-C13H8-CMe2-eta (5)-C5H3(CH2CH2NR2)]ZrCl2 (R = Me (2a), Et ( 2b), Pr-i (2c)) and [eta (5)-C13H8-SiMe2-eta (5)-C5H3(CH2CH2NR2)]ZrCl2 (R = Me (4a), Et (4b), Pr-i (4c)) have been prepared. Activation of 2a-c and 4a -c with excess methylalumoxane results in the formation of catalytically ac tive species for the polymerization of ethylene and propylene. (C) 2001 Els evier Science B.V.
