  摘要：

  铁基催化剂的2,6-双[1-（4-溴-2,6-二甲基苯基亚氨基）乙基] -pyridineiron（II），氯化1，已被成功地合成和表征。评估了其在不同温度和Al / Fe比下乙烯聚合的催化活性，并与2,6-双[1-（2,6-二甲基苯基亚氨基）乙基]吡啶铁（II）2的催化活性进行了比较。结果表明，催化剂1的催化活性高度依赖于乙烯聚合中使用的MAO的量，并且在约20℃下呈现最大值。

• Influence of the para-substitution in bis(arylimino)pyridine iron complexes on the catalytic oligomerization and polymerization of ethylene

  A series of nine bis(arylimino)pyridine iron complexes containing halogen or alkynyl substituents in their ligand frameworks was synthesized and characterized. After activation with methylalumoxane (MAO), these catalysts oligomerize or polymerize ethylene to give highly linear products. The introduction of halogen or alkynyl substituents in the para-position of the iminophenyl rings has a great influence on the polymerization activities of the corresponding iron complexes.
