A base-mediated aerobic oxidation of alkylbenzimidazoles for the preparation of carboxylic acids is described. A number of aliphatic carboxylic acids have been prepared in good to excellent yields via a C–C bond rupture process. Preliminary mechanistic studies suggest the reaction undergoes a radical pathway initiated by strong bases such as potassium amide. This type of transformation provides an
描述了用于制备羧酸的烷基苯并咪唑的碱介导有氧氧化。许多脂肪族羧酸已经通过 C-C 键断裂过程以良好至优异的产率制备。初步机理研究表明,该反应经历了由强碱(如氨基钾)引发的自由基途径。这种类型的转化为获取重要的羧酸部分提供了一种替代策略。
