A novel and efficient grafting method for covalent bonding of functional organic molecules to silica or glass surfaces has been developed. The protocol employs transition-metal-catalyzed reactions of vinylsilanes with surface hydroxyl groups. Dimethyldivinylsilane can be used in this procedure as a linker in which one vinyl group is used for direct C-C bond formation with a functional organic molecule and the other is employed to immobilize the alkylsilyl group onto the hydroxyl surface of the solid support.
