A new method for Huisgen [3+2] cycloaddition synthesis of 1,4- and 1,4,5-substituted-1H-1,2,3-triazoles was reported. The reaction was catalyzed by the product of thermolysis of copper (II) poly-5-vinyltetrazolate. Heterogeneous catalyst includes copper nanoparticles which supported on polymeric matrix. It presents recovered and recycled catalyst and the catalyzed reaction proceeds in aerobic conditions
报道了一种新的Huisgen [3 + 2]环加成合成1,4-和1,4,5-取代的-1 H -1,2,3-三唑的新方法。该反应由聚(5-乙烯基四唑酸铜)铜(II)的热解产物催化。非均相催化剂包括负载在聚合物基质上的铜纳米颗粒。它提供了回收和再循环的催化剂,催化反应在需氧条件下于室温在水性介质中进行。
