Preparation of triazoles using heterogenous catalysts containing transition metals such as cupper

New solid catalyst, consisting of cupper (II) supported on amine functionalized polystyrene (Cu-PS– amine) has been developed via immobilizing cupper (II) salt onto an amine-functionalized Cu-PS–amine surface. The prepared catalyst could be dispersed homogeneously in water and further used as a heterogeneous, reusable and efficient catalyst for the synthesis of 1,4-disubstitued 1,2,3-triazoles by reaction of benzyl bromides, phenyl acetylenes and sodium azide.
