Disclosed herein are ketal compounds, oligomers, and polyketals that are obtained in both high purity and high yield. These ketals and polyketals are utilized for their ability to readily release small chemical molecules, preferably fragrance molecules. Also disclosed are the utility of ketals and polyketals as delivery vehicles for controlled release of fragrances over time and/or on demand.
The present invention relates to compounds of formula (I) as properfume compounds. In particular, the present invention relates to a method to release a compound being a carbonyl of formula (II), a formate ester of formula (III) and/or an alcohol of formula (IV), by exposing the compound of formula (I) to an environment wherein it is oxidized. Moreover, the present invention relates to a perfuming composition and a perfume consumer product comprising at least one compound of formula (I).

A method of preparing an alkoxy-functional organosilicon compound is provided. The method comprises reacting (A) an initial organosilicon compound and (B) an alcohol component in the presence of (C) a catalyst, thereby preparing the alkoxy-functional organosilicon compound. The initial organosilicon compound (A) comprises at least one alkoxysilyl group. The alcohol component (B) comprises an organic alcohol. The catalyst (C) comprises (C1) an ammonium carboxylate compound or (C2) a titanate compound. A reaction product comprising an alkoxy-functional organosilicon compound prepared in accordance with the method, and a composition comprising the reaction product, are also provided. The alkoxy-functional organosilicon compound, and the reaction product and composition comprising the same, are prepared in increased purity under functional group-tolerant conditions.
