The reactions of 2-alkyl-, 2,5-dimethyl-, and 3,3,5-trimethylcyclohexanone with iodine/copper(II) acetate in boiling aqueous acetic acid gave the respective 3-alkyl-, 3,6-dimethyl-, and 3,5,5-trimethyl-1,2-cyclohexanediones in 40-70% yields. This new synthetic method is more convenient than the methods used heretofore.
2-烷基、2,5-二甲基和3,3,5-三甲基环己酮与碘/醋酸铜(II)在沸腾的水合醋酸中反应,得到了相应的3-烷基、3,6-二甲基和3,5,5-三甲基-1,2-环己二酮,产率为40-70%。这种新的合成方法比之前使用的方法更加方便。
