cycloheptene, gave by that reaction conjugated ketones, i.e. the corresponding 1-acetylcycloalkenes, as the only unsaturated carbonyl compounds in moderate-to-good yields. Under the same reaction conditions their 1-methyl derivatives gave mixtures of the corresponding conjugated and β,γ-unsaturated isomeric ketones in which unconjugated compounds predominate. In both cases unsaturated ketones were accompanied
研究了使用牺牲铝阳极通过电化学生成催化剂对一些脂环族和脂肪族烯烃的酰化。在酰化剂(乙酰氯或酸酐)的存在下,在适当电解质(四烷基铵盐)的二氯甲烷溶液中电解基材。因此,未取代的环烯烃,即环己烯和环庚烯,通过该反应得到共轭酮,即相应的 1-乙酰环烯烃,作为唯一的不饱和羰基化合物,产率中等至良好。在相同的反应条件下,它们的 1-甲基衍生物得到相应的共轭和 β,γ-不饱和异构酮的混合物,其中非共轭化合物占主导地位。在这两种情况下,不饱和酮都伴随着不同数量的副产物。末端脂肪族烯烃(1-己烯、1-庚烯和 1-十二烯)仅提供具有正常骨架的共轭酮,但产率较低。环己基酰化...
