A method for preparing a silyl ester compound is disclosed. The silyl ester compound may be a silane monomer or siloxane oligomer. The silyl ester compound may be hydro silylated with a polyorganohydrogensiloxane to form a silyl ester protected product, which may then be de-protected with water to prepare a carboxy-functional polyorganosiloxane.
