Abstract
Disclosed herein are methods for a simple process to make 3-aminoorgano functional silanes and siloxanes, free from isomers, by the use of commonly available materials. One embodiment of such a method comprises reacting aminoorgano functional silanes with hexamethyldisilazane in the presence of an acidic catalyst to produce a cyclic gamma-functional aminoorganic silane and beta isomers; separating the cyclic gamma-functional aminoorganic silane and the beta isomers; and converting the separated cyclic gamma-functional aminoorganic silane to pure gamma-aminoalkylsilane or pure aminoorganic siloxane. Also disclosed herein are cyclic derivatives of gamma-functional aminoorganic silanes.
