The reaction of Cp′2Th(CH3)2 (Cp′ = η5-(CH3)5C5) with HNnBu3+B(C6F5) 4- yields the crystallographically characterized, cationic thorium alkyl Cp′2ThCH3+B(C6F 5)4-. The B(C6F5)4- anion is weakly coordinated, the NMR spectroscopic parameters are similar to those of Cp′2Th(CH3)2 adsorbed on dehydroxylated alumina, and the complex is a highly active catalyst for ethylene polymerization and 1-hexene hydrogenation.
