title: Supported cationic complexes: selective preparation and characterization of the well-defined electrophilic metallocenium cation [[triple bond]SiO-B(C6F5)3]- [Cp*ZrMe2(Et2NPh)]+ supported on silica.
abstract: The reaction of Cp*ZrMe3, 1, with the heterogeneous activator [[triple bond]SiO-B(C6F5)3]- [HNEt2Ph]+, 2, has been investigated to generate, by an irreversible process of methane elimination, the well-defined cationic silica-supported metallocenium species [[triple bond]SiO-B(C6F5)3]- [Cp*ZrMe2(NEt2Ph)]+, 3, as an active olefin polymerisation catalyst.
