Abstract

A series of sulfur-bridged bis(2-indenyl) zirconocenes were synthesized and tested for ethylene/1-octene co- polymerization and 1-decene oligomerization. Zirconocene bearing two 5,6-positioned methyl substituents in indenyl moieties, distant from the metal center, appeared to be an active catalyst producing 1-decene oligomers with high content of unsaturated vinylidene end groups, which is preferable for post-functionalization.

硫桥接双（2-茚二基）锆茂烯及其在烯烃聚合中的性能

合成了一系列硫桥接的双（2-独立基）锆茂烯，并对其进行了乙烯/1-辛烯共聚和1-癸烯低聚反应测试。在远离金属中心的独立基上含有两个5,6位甲基取代基的锆新统似乎是一种活性催化剂，可以产生具有高含量不饱和偏乙烯端基的1-癸烯低聚物，这有利于后功能化。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
