Preparation of amino-functional organosilicon compounds

A process for preparing an amino-functional organosilicon compound, the process comprising:

• I) combining, under conditions to catalyze reductive amination reaction, starting materials comprising an aldehyde-functional organosilicon compound, wherein the aldehyde-functional organosilicon compound has, per molecule, at least one aldehyde-functional group covalently bonded to silicon via a silicon-carbon bond, and the aldehyde-functional group has formula:
• where G is a divalent hydrocarbyl group free of aliphatic unsaturation that has 2 to 8 carbon atoms, an amine source, a hydrogenation catalyst, hydrogen, and optionally a solvent, thereby forming a reaction product comprising the amino-functional organosilicon compound having at least one amino-functional group covalently bonded to the silicon atom via the silicon-carbon bond.
