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.
