substrate scope including aliphatic and aromaticalkenes/alkynes from which aliphatic C8‐alkenones, C8‐alkenals and aromatic nitroalkenes were the preferred substrates. By comparing alkenes and alkynes, a ∼2‐fold lower conversion towards alkynes was observed. Furthermore, it could be shown that the alkyne reduction proceeds via a slow reduction of the alkyne to the alkene followed by a rapid reduction to

The present invention relates to a delivery system based on photosensitive acetal or ketal compounds capable of liberating upon exposure to light an active volatile carbonyl compound in a controlled manner from a surface into the surrounding. The delivery system can be used to release active substances such as flavors, fragrances, malodor counteractants, insect attractants or insect repellents. The invention also relates to the use of said acetal or ketal compounds in perfumery, as well as in perfuming compositions or perfumed consumer articles.
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 perfumed consumer product comprising at least one compound of formula (I).

The present invention relates to a perfuming composition comprising at least two properfume compounds selected from the group consisting of a pro-perfume compound releasing a perfume compound upon exposure to light, a pro-perfume compound releasing a perfume compound upon exposure to air/oxygen, a pro-perfume compound releasing a perfume compound upon exposure to heat, a pro-perfume compound releasing a perfume compound upon exposure to moisture and a pro-perfume compound releasing a perfume compound upon exposure to enzymes. The present invention further concerns a perfumed consumer product comprising the inventive perfuming composition, as well as the use of the inventive perfuming composition for improving, enhancing, conferring and/or modifying the fragrance impression and/or fragrance intensity of a consumer product.
