Abstract
Iminoorganosilanes may be prepared by reacting aminoorganosilanes with organoimines by an amine exchange reaction. The resultant iminoorganosilanes can then be catalytically reduced to produce secondary and tertiary amino silanes. Imidoorganosilanes can be prepared by a similar amine reaction between aminoorganosilanes and organoimides. The imidoorganosilanes can also be reacted to produce tertiary amines. Water-sensitive silane reactants may be employed to yield water-sensitive imino, imido, or amino silane products.
Claims22
A process for preparing a silane compound comprising the steps of
- a) providing an organo imine compound which is the reaction product of ammonia or a primary amine and an organic carbonyl compound;
- and
- b) reacting said organo imine compound with an aminoorganosilane in an amine exchange reaction to produce an silylorganoimine compound.
A process for preparing a silane compound comprising the steps of
- a) providing in an organo imide compound which is the reaction product of ammonia or a primary amine and an organic anhydride compound;
- and
- b) reacting said organo imide compound with an aminoorganosilane in an amine exchange reaction to produce a imidoorganosilane compound.
