| 摘 要： | 设计合成了对硝基苯乙醇、对硝基苯氧乙酸、对硝基苯氧丙酸、对硝基苯氧丁酸、对硝基苯丁醚等一系列的对硝基芳香醚,并以它们作为研究对象,对碱性介质中芳醚键的稳定性进行了研究。发现了对硝基苯氧丙酸亲核取代的异常情况,推测是分子内邻基参与的亲核取代反应。

| Abstract: | A series of p-nitro aryl ethers(p-nitrophenoxy ethanol 、p-nitrophenoxy acetic acid 、p-nitrophenoxy propionic acid、p-nitrophenoxy butyric acid、p-nitrophenoxy butyl ether)have been synthesized,which are used as the studied substrate and their stability of aryl etherbond in the alkaline mediumhas been studied.The abnormal behaviour whichhappened in the nucleophilic substitution process of p-nitrophenoxy propionic acidhas been discovered.The mechanism is proposed as an intramolecular nucleophilic substitution by neighboring group participation. |

| Keywords: | p-nitro aryl ether nucleophilic substitution p-nitrophenoxy propionic acid alkaline medium neighboring group participation |
