摘要：

Anions of the type [C2B9H11)2M]- (M = Fe, Co, Ni) are suitable for use as ''noncoordinating'' anions with [Cp2ZrMe]+ cations. Catalysts generated from Cp2ZrMe2 and [PhNMe2H][(C2B9H11)2M] are active for the polymerization and copolymerization of ethylene and alpha-olefins. Spectroscopic examination of the cobalt complex indicates that the anion is weakly coordinated to the metal at room temperature. At low temperatures, however, the aniline-coordinated adduct [Cp2ZrMe(NMe2Ph)]-[(C2B9H11)2M] present. These catalysts are active in toluene or hexane for the polymerization of ethylene and the copolymerization of ethylene and 1-butene.
