A novel synthetic method for the preparation of aliphatic aldehydes from the corresponding carboxylic acids via 1,3‐dimethylbenzimidazolium salts is provided. 1,3‐Dimethylbenzimidazolium salts were rapidly reduced with sodium/ethanol and then hydrolyzed with hydrochloric acid to obtain aliphatic aldehydes, in which the 1,3‐dimethylbenzimidazolium salts can be readily achieved from the corresponding
提供了一种新的合成方法,可通过1,3-二甲基苯并咪唑鎓盐从相应的羧酸制备脂肪族醛。1,3-二甲基苯并咪唑鎓盐用钠/乙醇快速还原,然后用盐酸水解,得到脂肪族醛,其中1,3-二甲基苯并咪唑鎓盐可以很容易地由相应的羧酸制得。讨论了1,3-二甲基苯并咪唑鎓盐与钠/乙醇的还原反应机理。
