The present invention relates to the use of specific organic compounds as flavor and fragrance material. Furthermore the invention relates to new specific organic compounds and their synthesis, as well to flavor and fragrance formulations comprising at least one of the specific organic compounds.
The present invention provides a process for the oxidation of straight-chain, branched-chain or cyclic alkanes of 1-20 carbon atoms and benzene derivatives represented by the following formulas (1) - (2). The alcohols and ketones obtained by the oxidation of the alkanes mentioned above and those by the oxidation of the benzene derivatives mentioned above represented by the following formulas (3) - (6) are important as basic starting materials in producing various chemical products including resins, such as nylon and polyester, pharmaceuticals, agricultural chemicals, perfumes, dyes, etc.

A process for hydrogenation of a conjugated diene polymer. The conjugated diene polymer in an inert organic solvent is brought into contact with hydrogen in the presence of a hydrogenation catalyst composition to selectively hydrogenate the unsaturated double bonds in the conjugated diene units of the conjugated diene polymer. The hydrogenation catalyst composition includes: (I) a titanium compound; (II) a compound represented by formula (II):
