Organosilicon compounds containing at least one acylamino-substituted hydrocarbon radical are prepared by reacting an organohydroxysilicon compound containing at least one silicon-bonded hydroxy radical with a base to yield a silanolate. The silanolate is reacted with a cyclic amino-silane compound to form a siloxyalkylamide that is then reacted with an acyl chloride to give the desired product. All reactions can be carried out in a single reaction vessel using a nonaqueous solvent.

Composés organosiliciés renfermant au moins un radical hydrocarboné acylaminé; ils sont préparés par réaction d'un composé organohydroxysilicié contenant au moins un radical hydroxy lié à du silicium, avec une base pour former un silanolate. On fait réagir ce dernier avec un aminosilane cyclique pour former un siloxyalkylamide, que l'on fait réagir à son tour avec un chlorure d'acyle pour obtenir le produit recherché. Toutes les réactions sont effectuées dans une seule cuve de réaction avec un solvant non aqueux.
