In the presence of N,N,N’,N’-Tetramethylethylenediamine (TMEDA) and LiOH, a new FeCl3 catalyzed the ipso-hydroxylation of arylboronic acids for the synthesis of phenols is developed. When a series of electron-rich and electron-deficient arylboronic acids are reacted in DMF at room temperature for 20 min in the open air and in the presence of FeCl3, the desired Phenols were obtained in good yields. Furthermore, no matter substituted phenyl or heterocyclic boronic acids, were all found to tolerate the reaction conditions.%在FeCl3催化及TMEDA,LiOH参与下,利用TEMPO作为氧化剂建立一种由芳基硼酸转化为酚的新方法。通过对金属催化剂的种类、反应溶剂和温度等因素的考察,最终确定反应的最优条件为5% mol FeCl3作催化剂、DMF为溶剂、敞口条件下室温反应20 min。该反应具有一定的底物普适性,反应体系适宜于苯基硼酸和杂环硼酸。
