Abstract:

1,2,3-Triazole derivatives have gained attention as an attractive heterocyclic compound with antifungal, antibacterial, anti-HIV, anticonvulsants and anti-allergic activities. The copper-catalyzed azide-alkyne cycloaddition reaction (CuAAC) is an example of click reaction, since is a simple method for synthesized triazoles with an wide scope, high yields in mild conditions. Combining with concept of green chemistry, the CuAAC click reaction has been improved by immobilization of copper species onto various supports. In this work, it was studied the recovery and reuse of copper in CuAAC reaction by immobilizing it in alginate spheres (Alg-CuSO4).
