    Abstract: A method for releasing one or more active volatile aldehydes or ketones from 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 environment. 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 such acetal or ketal compounds in perfumery, as well as in perfuming compositions or perfumed consumer articles.

    Abstract: The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one β-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an α,β-unsaturated ketone, aldehyde or nitrile. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. (I) wherein: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous α,β-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II′) in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II′).
