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, an amine source, a hydrogenation catalyst, hydrogen, and optionally a solvent, thereby forming a reaction product comprising the amino-functional organosilicon compound;
• where the aldehyde-functional organosilicon compound comprises
• where each RAld is an independently selected aldehyde group of 3 to 9 carbon atoms, and each R4 is independently selected from the group consisting of an alkyl group of 1 to 18 carbon atoms and an aryl group of 6 to 18 carbon atoms.
