Eleven novel 1,3-bis(6-aryl-1,2,4-triazolo[3,4-b][1,3,4]thiadiazol-3-yl)-methoxy}benzenes have been synthesised in high yields by the condensation of 5,5'-[1,3-phenylene-bis(oxymethylene)]bis(4-amino-3-mercapto-1,2,4-triazole) with substituted benzoic acids in the presence of phosphorus oxychloride under microwave irradiation. Compared with the conventional heating method, this method is facile, rapid and efficient. The structures of all new compounds were characterised by 1H NMR, IR, MS and elemental analysis.
在氧氯化磷存在下,通过缩合 5,5'-[1、双(4-氨基-3-巯基-1,2,4-三唑)与取代苯甲酸的缩合反应。与传统的加热法相比,该方法简便、快速、高效。所有新化合物的结构均通过 1H NMR、IR、MS 和元素分析进行了表征。
