Dodeca-(3trans, 5trans)-diene-2-one and 4-Δ1-cyclohexenyl-but-(3trans)-ene-2-one were prepared, whereas the syntheses of dodeca-(3cis,5trans)-diene-2-one and 4-Δ1-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
Dodeca-(3trans,5trans) -二烯-2-酮和4-Δ 1
环己烯基-丁- (3trans) -烯-2-酮制备,而dodeca-的合成(3cis,5trans) -二烯-2- -1和4-Δ1-
环己烯基-但是-(3cis)-烯-2-实际上失效了。相应炔属酮的部分氢化得到含有反式酮,烯醇醚,未改变的起始原料和比二烯酮更高的饱和度的化合物的混合物。无法确定检测到顺式酮。
