摘要

Group 4 metal metallocene-type systems have attracted intense interest due to their ability to act as highly active olefin polymerization catalysts in conjunction with various cocatalysts. 1 Substantial evidence is now present for the role of cationic 14-electron metallocene alkyls as active catalyst species. 2 There is a significant influence of the complementary anion on activity and selectivity of these catalysts. 3 A potential means of directing cation-anion ...
