1. A method of preparing an alkoxy-functional organosilicon compound, said method comprising:

reacting via transalkoxylation (A) an initial organosilicon compound having at least one alkoxysilyl group and an epoxide group, an ester group, an anhydride group, or an acryloxy group and (B) an alcohol component comprising an organic alcohol in the presence of (C) a catalyst comprising (C1) an ammonium carboxylate compound, thereby preparing the alkoxy-functional organosilicon compound.
