CA 2129958

This invention provides a class of cyclic silylureas and a process of preparing them, which process comprises reacting a cyclosilazane with an isocyanate containing moiety; a class of cyclosilazanes and process for making them, which process comprises heating an aminoalkylalkoxysilane in the presence of a basic catalyst at a temperature less than 100 °C at subatmospheric pressure; and aminoalkylalkoxysilanes and a process for making them, which process comprises reacting a nitrile and a vinylsilane while heating in the presence of a base selected from the group consisting of (a) an alkali metal, (b) alkali metal alkoxide, (c) an alkali metal amide, (d) an alkali metal hydride and (e) mixtures thereof to, form a reaction product which is subsequently hydrogenated.

Classe de silylurées cycliques et méthode pour les préparer, consistant à faire réagir un cyclosilazane avec un groupe isocyanate; classe de cyclosilazanes et méthode de préparation, consistant à chauffer un aminoalkylalcoxysilane en présence d'un catalyseur basique, à une température inférieure à 100 degrés C et sous une pression subatmosphérique; aminoalkylalcoxysilanes et méthode de préparation, consistant à faire réagir, en chauffant, un nitrile et un vinylsilane en présence d'une base choisie parmi (a) un métal alcalin (b) un alcoxyde de métal alcalin, (c) un amide de métal alcalin, (d) un hydrure de métal alcalin et (e) des mélanges de ceux-ci, pour former un produit de réaction, qui sera ultérieurement hydrogéné.
