The heterogeneous gas/solid reaction of 3-chloropropyltrimethoxysilane with the solid alkoxide bases lithium, sodium and potassium methoxide has been studied at 150 and 190 deg C.The lithium compound yields solely 3-methoxypropyltrimethoxysilane in a convenient, high yield reaction.Reaction with sodium methoxide gave products resulting from substitution at silicon and carbon as well as elimination products.Potassium methoxide is the least reactive of the three bases studied and gave products similar to those of the sodium methoxide system.Under the conditions of heterogeneous reaction, some cleavage of the chloropropyl group is observed.It is suggested that this cleavage follows base-induced elimination to give allyltrimethoxysilane.
