Copper-anchored polysulfonamide-modified UiO-66-NH2/sodium alginate nanocatalyst for sustainable synthesis of 1,2,3-triazoles

Abstract

An effective nanocomposite comprising a metal–organic framework and porous polysulfonamide-sodium alginate (SA-PS) was developed for phenyl triazole production. The Cu(I) ions were uniformly distributed on the as-prepared UiO-66-NH₂@SA-PS matrix, coordinated by sulfonamide groups in a bidentate bridging pattern (UiO-66-NH₂@SA-PS/CuI). The nanocatalyst UiO-66-NH₂@SA-PS/CuI demonstrated exceptional performance in the synthesis of 1,2,3-triazole derivatives, facilitating high product yields in the reaction of various aryl boronic acids, phenylacetylene, and sodium azide under mild conditions.
