In this work, a method has been developed for the synthesis of magnetic chitosan functionalized trichlorotriazine-5-amino-1H-tetrazole copper(II) complex (Fe₃O₄@CS-TCT-Tet-Cu(II)). The synthesized Fe₃O₄@CS-TCT-Tet-Cu(II) was characterized using XRD, EDS, elemental mapping, STEM, FT-IR, TG/DTA, FFT, ICP-MS, and TEM analyses. Fe₃O₄@CS-TCT-Tet-Cu(II) was then applied in the synthesis of N-sulfonyl-N-aryl tetrazoles and 5-arylamino-1H-tetrazoles via the reaction of sodium azide with N-sulfonyl-N-arylcyanamides and arylcyanamides, respectively in DMF solvent. The synthesized Fe₃O₄@CS-TCT-Tet-Cu(II) can be recycled and reused for five cycles with no considerable loss of catalytic performance.

在这项工作中，开发了一种用于合成磁性壳聚糖功能化三氯三嗪-5-氨基-1 H-四唑铜 (II) 配合物 (Fe ₃ O ₄ @CS-TCT-Tet-Cu(II)) 的方法。合成的 Fe ₃ O ₄ @CS-TCT-Tet-Cu(II) 使用 XRD、EDS、元素映射、STEM、FT-IR、TG/DTA、FFT、ICP-MS 和 TEM 分析进行表征。Fe ₃ O ₄ @CS-TCT-Tet-Cu(II)随后通过叠氮化钠与N-磺酰基-反应合成N-磺酰基-N-芳基四唑和5-芳基氨基-1H-四唑。N-芳基氰胺和芳基氰胺，分别在 DMF 溶剂中。合成的 Fe ₃ O ₄ @CS-TCT-Tet-Cu(II) 可以回收再利用五个循环，催化性能没有显着损失。
