Synthesis of triazoles by iodine supported on heterogenous catalysts

Polystyrene functionalized by amines was prepared. Iodine was then supported on this organic polymer and used as a stable and efficient heterogeneous catalyst for the synthesis of 1,4-disubstitued 1,2,3-triazoles by reaction of N‑Tosylhydrazones with Anilines under Metal-Free and Azide-Free Conditions.
