Abstract
Organomonoalkoxy/monohydroxy silanes, particularly halogenated or aklenylated organomonoalkoxy (or monohydroxy) silanes, which are useful intermediates in organic syntheses, are prepared by reacting an alkoxysilane with an organometallic compound suited for substituting at least certain of the alkoxy functions of the alkoxysilane with a monovalent hydrocarbon radical other than alkoxy and co-preparing a metallic alkoxylate by-product capable of denaturing the substituted silanes thus obtained, including contacting the metallic alkoxylate with at least one agent (A) reactive with the alkoxy functions of the alkoxylate to generate one or more species inert relative to the alkoxysilane, such agent (A) being selected from among the electrophile and/or mineral acid groups.
