Abstract
A silicon halide such as methyl trichlorosilane is reacted with an alcohol such as isopropanol and an oxime such as methyl ethyl ketone oxime. Byproduct oxime hydrohalide is formed in all cases. With higher amounts of alcohol, alkoxysilane (e.g. methyl triisopropoxysilane) is the sole or major product. With lower amounts of alcohol, alkoxy-oxminosilanes (e.g. methyl diisopropoxy(methyl ethyl ketoximo)silane and methyl isopropoxy bis(methyl ethyl ketoximo)silane) are the major products.
