Magnetically recoverable and reusable CuFe2O4 nanoparticles are shown to be highly efficient catalysts for the one-pot synthesis of biologically important 1,4-diaryl-1,2,3-triazoles starting from boronic acids, sodium azide, and acetylenes. The use of aqueous reaction medium at room temperature, the low cost and facile recovery of the catalyst by application of an external magnetic field, and consistently
磁性可回收和可重复使用的 CuFe2O4 纳米颗粒被证明是一种高效的催化剂,用于从硼酸、叠氮化钠和乙炔开始一锅法合成生物学上重要的 1,4-二芳基-1,2,3-三唑。在室温下使用水性反应介质、通过施加外部磁场实现催化剂的低成本和容易回收,以及至少连续三个循环的持续高催化效率使该协议在操作上具有吸引力。
