The synthesis of 4-alkyl-4-trihalogenomethylcyclohexa-2,5-dienone derivatives by the application of the Zincke–Suhl reaction on p-alkyl-phenols is described. In some cases, only benzophenone derivatives were obtained. When the dienones were treated with reagents like phosphorus pentachloride and sulphuric acid, migration of the groups from the gem-C-atom occurred giving rise to halogenated benzoic
描述了通过在对烷基苯酚上应用Zincke-Suhl反应合成4-烷基-4-三卤代甲基环己2,5-二烯酮衍生物。在某些情况下,仅获得二苯甲酮衍生物。当二烯酮用五氯化磷和硫酸之类的试剂处理时,基团从宝石-C原子发生迁移,生成卤代苯甲酸衍生物,在大多数情况下,卤代苯甲酸衍生物是通过独立途径合成的。在少数情况下,在与五氯化磷反应期间也观察到烷基的消除。
