Sulfur-bridged bis(2-indenyl) zirconocenes and their performance in olefin polymerization

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.
