Immobilization of molecular catalysts onto a solid support is a promising strategy to facilitate the separation of the catalyst from the products. Based on this idea, our group, in recent years, has been pursuing silica gel supported zirconium (IV) complexes to serve as Lewis acids as catalysts for C-C bond forming reactions. Reported here is an anchoring of polyphenylcyclopentadienyl zirconium (IV) (1) on SiO₂ by three different approaches: a one-pot reaction method using a mixture of C₅Ph₅H, Zr(NMe₂)₄ and SiO₂, a direct way by reacting a piano-stool complex (C₅Ph₅Zr(NMe₂)₃) with SiO₂, and a multi-step surface grafting approach that uses amine elimination from a Zr(N(Me₂))₄ precursor. The characterization results show that anchorage of the zirconium amides on the prepared surface was carried out by the amine elimination route. Current work focuses on the effectiveness of 1 as a catalyst for the [4+2] cycloaddition reaction, the reactive properties with chiral ligands and the temperature dependence of silica gel coordination modes.
