Abstract

Reversible C6F5 transfer takes place between the boron centers in the anion formed by methide abstraction from [MeZr{N(SiMe3)2}3] or [Cp2ZrMe2] (L(n)M-CH3 in the reaction scheme) by the perfluorinated diborane 1. The solution chemistry of the metallocenium ion pairs formed from 1 and [Cp2ZrMe2] is correlated with the observed ethylene polymerization behavior of 1 in comparison to the monoborane B(C6F5)3, the related diborane 1,2C6H4[B(C6F5)2]2, and the 9,10-diboraanthracene compound 9,10-(C6F5)2C12B2F8.
