2-propargylcyclohexanone with alcohols, amines, or amino alcohols, followed by base treatment (Scheme 1). Phenolic ethers and N-phenylated polyalkyl aromatic compounds are shown to be in the scope of the demonstrated reaction (Table). The proposed mechanism suggests that the unsaturation in another part of the molecule (propargyl-group equivalent) is transferred into the cyclohexane ring to yield a benzene
烷基苯是在基本条件下通过单锅,无过渡金属的偶联方法首次从脂肪烃中合成的。该方法包括两个步骤:将2-溴丙-2-烯基或2-炔丙基环己酮与醇,胺或氨基醇缩合,然后进行碱处理(方案1)。酚类醚和N-苯基化聚烷基芳族化合物显示在已证实的反应范围内(表)。提出的机理表明分子另一部分的不饱和度(炔丙基等价基团)通过一系列质变位移转移到环己烷环中生成苯环。
