N-Silyldimethylamines are efficient silylating agents for the chemical surface modification of hydroxylated silicon dioxide preparations. The synthesis of chloro(5-X-3,3-dimethylpentyl)-dimethylsilanes and their conversion to the corresponding (dimethylamino) silanes are described, where X is a methoxy, methoxymethoxy, cyano or dimethylamino group. The bulky substituent forms a two stage protecting layer at the surface. The second stage hinders the access of nucleophiles to the silicon atom resulting an enhanced hydrolytic stability.
