Abstract

Reaction of tBuCH2CH(BCl2)2 with LiC6F5 yields the binuclear organo-Lewis acid tBuCH2CH- [B(C6F5)2]2, which can be converted with KEt3BH, followed by metathesis, into the salt [HNnBu3]+{tBuCH2- CH[B(C6F5)2]2H}-. Reaction of this salt with Cp′2Th- (CH3)2 (Cp′ = η-Me5C5) yields the cationic metallocene complex Cp′2ThCH3+{tBuCH2CH[B(C6F5)2]2H}-(5), which is a highly active catalyst for ethylene polymerization and 1-hexene hydrogenation. The THF adduct, Cp′2Th- (CH3)THF+{tBuCH2CH[B(C6F5)2]2H}-, has been characterized by X-ray diffraction.
