A novel class of odorants is described where the odor is associated with the interaction of two functional groups, one being an H-donor (AH function), and the other an H-acceptor (B function). Generally, odor occurs only if the distance between the two structural elements (AH/B system) is less than 3 Å. Bifunctional derivatives of the p-menthane and iridane series served as models for deriving this

The Gif oxidation systems cleave methylidene olefins into the ketone or aldehyde and formaldehyde. This is considered to be a further manifestation of an Vfe oxenoid species. Similarly, more substituted olefins are oxidized to the corresponding unsaturated ketones or aldehydes. The oxidation of limonene afforded the ketone 24 resulting from methylene cleavage and racemic carvone 25. The latter is considered
