摘要：

High electrophilicity and polymerization activity as well as ion-pairing effects not based on the bridging hydrogen atoms are the most notable characteristics of the cation in 2, a model compound for Ziegler-Natta catalysts. This hydrido complex is accessible by hydrogenolysis of 1 or by hydride abstraction from 3. [GRAPHICS]
