I. Deposition of alkylmagnesium reagents onto porous silicas bearing a known amount of accessible hydroxyl groups results in alkylmagnesium-modified supports for which the grafting stoichiometry can be deduced. TiCl4 and/or VOCl3 are attached to these ‘passivated’ silica surfaces by non-protolytic grafting, to yield the immediate precursors of certain Ziegler-Natta catalysts. The nature of the transition metal sites (nuclearity, oxidation state, ligand complement) has been studied using a combination of elemental analysis, XPS, EPR, XAS, and analysis of volatile organic products.

II. Amorphous silica-alumina has also been studied as a catalyst support, notably in the deposition of perrhenate with SnMe4. Since SnMe4 does not react with silica under mild conditions (i.e., room temperature), its reaction with silica-alumina itself allows us to probe selectively the elusive Brønsted acidic hydroxyls of silica-alumina.
