Abstract

Asymmetric alkylmethyl zirconocene derivatives were readily synthesised from Cp₂ZrCl(CH₃), and the appropriate alkyllithium reagent. The alkyl groups contain a silyl functionality on the β-position. These asymmetric dialkyl zirconocenes were successfully activated by B(C ₆F₅)₃, selectively abstracting the methyl group. The clear difference in the ¹³C NMR resonances, due to the alkyl groups on the cationic zirconocene made it possible to conclude that selective activation of this class of compounds was possible.
