Abstract:
A process for preparing a support material having an increased number of reactive groups, comprisinga) reacting an oxygen-containing inorganic material in an inert aprotic polar or inert aprotic nonpolar solvent with a strongly basic reagent containing one or more alkali metal or alkaline earth metal (M) atoms, the resultant OM groups formed on the surface of the inorganic material optionally being set free by acidifying with an organic or inorganic acid to form OH groups, and b) reacting the OH and/or OM groups formed on the surface of the inorganic material with coreactive groups of a ligand, catalyst or cocatalyst, wherein said ligand, catalyst and cocatalyst comprises a functional organic group, and/or c) modifying the OH and/or OM groups formed on the surface of the inorganic material by chemisorptively binding coreactive groups, forming a surface comprising chemisorptively bound, functional organic groups.
