two-step, one-pot reaction of aldehydes with the CAN/LiBr oxidation system under solvent-free conditions followed by the addition of methanol affords methyl α-bromocarboxylates. The oxidation of aldehydes with methanol using this system gives only methyl esters. A facile method, which does not require special equipment, was developed for the synthesis of 2-bromoesters from aliphatic aldehydes with carbon
在无溶剂条件下,醛与CAN / LiBr氧化系统进行两步一锅反应,然后添加甲醇,得到α-溴代羧酸甲酯。使用该系统用甲醇氧化醛只能得到甲酯。已开发了一种不需要特殊设备的简便方法,该方法可从碳链长度为5-10个原子的脂族醛合成2-溴酸酯。
