Summary

Mixed functionalized octa(n-alkyl/halogenalkylsilsesquioxanes) with different side chains has been prepared by acid-catalyzed cohydrolysis of n-alkyl- and halogenalkyltrichlorosilanes. The silsesquioxane mixtures were separated in preparative mounts with normal-phase HPLC. Mixed functionalized octa(n-alkyl/halogenalkylsilsesquioxanes) with different side chains are suitable examples of an organically modified silica gel. They can be modified by nucleophilic substitution of the halogen atom with -PPh2 and rhodium-phosphino complexes are be formed.
