Process for preparing silylorganoamines, which process comprises the following steps: (A) provision of silylorganoamines of the formula I: [R2a(R1O)3-aSiR3]nNH3-n in a reactor, (B) reaction of the silylorganoamines of the formula I in the presence of particulate metallic noble metal at a temperature in the range from 100° C. to 300° C. to form silylorganoamine products of the formula II: [R2a(R1O)3-aSiR3]yNH3-y, where each radical R1 and each radical R2 is selected independently from the group consisting of alkyl, aryl, aralkyl and cycloalkyl radicals having fewer than 20 carbon atoms; R3 is selected from the group consisting of divalent hydrocarbon radicals having fewer than 20 carbon atoms and a=0, 1, 2 or 3; n=1 or n=2 or n=1 and 2; and y=3.
