摘要

The reaction of ω-phenyl-1-bromoalkanes with cyclopentadienyl sodium, indenyl lithium or fluorenyl lithium forms ω-phenylalkyl-substituted ligand precursors in high yields. The corresponding anions react with zirconium tetrachloride to give ω-phenylalkyl-substituted zirconocene dichloride complexes. After activation with methylaluminoxane, these complexes are highly active catalysts for homogeneous ethylene polymerization. The ...
