  • Patent number: 11702432
    Abstract: A method of making an aminosilane, the method comprising: forming a reaction mixture comprising a hydridosilane, an amine and a dehydrogenative coupling catalyst in a reactor; subjecting the reaction mixture to conditions sufficient to cause a dehydrogenative coupling reaction between the hydridosilane and the amine to form the aminosilane and hydrogen gas; and venting the hydrogen gas; wherein the forming of the reaction mixture comprising the hydridosilane, the amine and the dehydrogenative coupling catalyst comprises continuously feeding the hydridosilane to the reactor containing the amine and the dehydrogenative coupling catalyst.
