Support materials with many reactive groups are obtained by reacting oxygen-containing inorganic materials with a strong base in inert aprotic solvent, optionally acidifying, and reacting with co-reactive groups of ligands, catalysts or cocatalysts, or modifying with co-reactive groups attached by chemisorption. A process for the production of support materials with a large number of reactive groups comprises: (a) reacting an oxygen-containing inorganic material with a strong base in inert aprotic polar or non-polar solvent, optionally acidifying with (in)organic acid to give free hydroxyl groups; (b) reacting the OH or OM groups with co-reactive groups of a suitable ligand, catalyst or cocatalyst; or (c) modifying the OH or OM groups with co-reactive groups attached by chemisorption, so as to produce a surface consisting of functional organic groups fixed by chemisorption. M = alkali or alkaline earth metal. An Independent claim is included for co-reactive support materials obtained by this process, in which various metals (M') with different substituents are attached to the same support. |
