Abstract
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.
