Reduction of 1-hexene with Cp3Ln/NaH (Cp = cyclopentadienyl, Ln = rare earth metals) in THF at 45°C, after hydrolysis, gives hexane. The reducing activity of Cp3Ln depends strongly upon the ionic radius of the trivalent rare earth ion. The activity and selectivity of early rare earths for 1-hexane reduction are higher than those of heavy rare earths. The Cp3Ln/NaH systems can be used to regioselectively
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, as well as to flavor and fragrance formulations comprising at least one of the specific organic compounds.
