  Dinuclear ansa zirconocene complexes containing a sandwich and a half-sandwich moiety as catalysts for the polymerization of ethylene

  摘要：

  Dinuclear ansa zirconocene complexes containing a half-sandwich and a sandwich moiety and their ligand precursors have been synthesized and characterized. After activation with methylalumoxane (MAO), these catalysts produce polyethylenes with bimodal molecular weight distributions in homogeneous and heterogeneous media. The catalyst performances and the polymer properties were compared with mono nuclear reference catalysts. (C) 2002 Elsevier Science B.V. All rights reserved.

  A series of doubly bridged bis(cyclopentadienyl) tetracarbonyl diiron complexes (7–13) have been synthesized by the reaction of the corresponding ligand (1–6) with Fe(CO)5 in refluxing xylene. It is unusual that the reaction of ligand (GeMe2)(GeMe2)(C5H4)2 (3) with Fe(CO)5 gave the complex (GeMe2)[(η5-C5H4)Fe(CO)]2(μ-CO)2 (10) as the main product which lost the GeMe2, only a small amount of the expected
