A study of the ultraviolet, infrared, and nuclear magnetic resonance spectra of Δ8,9-octahydro-7-quinolone (7a) and of the corresponding N- and O-ethyl derivatives 8 and 9, respectively, confirms that in cases of potential enonamine-enolimine tautomerism the enonamine form predominates. This also applies to vinylogous amides capable of intramolecular hydrogen bonding, such as 2-benzylaminomethylene- and 2-phenylaminomethylene-cyclohexanone, 10 and 11, respectively. Exeptions are only observed in cases where the enolimine form is stabilized by special factors, such as aromaticity.
