Abstract

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.

For compounds in which the geminal group is replaced by a single methyl or ethyl group, formation of a 6-ring could not be excluded theoretically. Practically, in this case also no ring closure occured. It is concluded that ring closure to carbocyclic compounds fails when the geminal dimethyl group
