Copper iodide nanoparticles on poly(4-vinyl pyridine) as new and green catalyst for multicomponent click synthesis of 1,4-disubstituted-1,2,3-triazoles in water
Poly(4-vinyl pyridine) supported nanoparticle of copper(I) iodide is reported as a green and recyclable catalyst for the regioselective synthesis of 1,4-disubstituted-1H-1,2,3-triazoles from benzyl halides, sodium azide and terminal alkynes in water. This catalyst can be recovered by simple filtration and recycled up to 8 consecutive runs without any loss of its efficiency. (C) 2012 Jalal Albadi.

The CuO/ZnO nanocatalysts are reported as efficient and recyclable catalysts for the regioselective synthesis of 1,2,3-triazoles from benzyl halides and terminal alkynes in water. The catalysts are synthesized by a co-precipitation method and characterized by BET surface area, XRD, SEM, TEM and EDS analysis. The effect of CuO loading, catalyst amount and solvent was investigated. The catalyst can be recovered by a simple filtration and applied in consecutive runs with no loss of activity.
