Dodeca‐(3trans, 5trans)‐diene‐2‐one and 4‐Δ 1 ‐cyclohexenyl‐but‐(3trans)‐ene‐2‐one were prepared, whereas the syntheses of dodeca‐(3cis,5trans)‐diene‐2‐one and 4‐Δ 1 ‐cyclohexenyl‐but‐(3cis)‐ene‐2‐one practically failed. Partial hydrogenation of the corresponding acetylenic ketones gave mixtures containing trans‐ketones, enolic ethers, unchanged starting material and compounds of higher degree of saturation than the dienones. Cis‐ketones could not be detected with certainty.
