Magnetically active CuFe2O4 catalyzed cascade synthesis of 4-Aryl-1H-1,2,3-triazoles under microwave irradiation starting from aromatic aldehydes, sodium azide and nitromethane has been developed and demonstrated here. The catalyst system needed for the purpose was prepared following a procedure by A. Dandiya et al. with a slight modification and was characterized using FT-IR, XRD, SEM-EDX and TEM
磁性活性CuFe 2 O 4催化4-芳基-1 H的级联合成在微波辐射下,从芳族醛,叠氮化钠和硝基甲烷开始的-1,2,3-三唑已被开发出来并在此进行了证明。该目的所需的催化剂体系是按照A.Dandiya等人的方法制备的。稍作修改,并使用FT-IR,XRD,SEM-EDX和TEM分析对其进行表征。所开发方法的最显着优势是出色的时间经济性来进行转换。其他功能还包括简单的操作程序,广泛的基材覆盖范围和催化剂的易于回收。已经测试了催化剂的可重复使用性,发现直到第六个循环都非常令人满意,而效率没有显着损失。所有合成的化合物均已使用FTIR,1 H和13进行了表征CNMR光谱,HRMS。
