Reusa ble Copper(II)-Terpyridine Complex Supported on Activated Multi-Walled Carbon Nanotubes as an Efficient Heterogeneous Catalyst for Synthesis of 2-Aryl/alkyl imidazole Derivatives

An expeditious and efficient route for the synthesis of 2-Aryl/alkyl imidazole derivatives by the reaction of aliphatic/aromatic aldehydes with o-phenylenediamines or benzil and NH4OAc in the presence of immobilized 4′-Phenyl-2,2′:6′,2′′-Terpyridine Copper(II) complex on activated multi-walled carbon nanotubes [AMWCNTs-O-Cu(II)-PhTPY] exhibited high catalytic activity for the transformation. The salient features of this method include a simple procedure, mildconditions, high yields, easy purification, and a recyclable catalyst. The heterogeneous catalyst was characterized by physico-chemical techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), Fourier-Transfrom IR spectroscopy (FT-IR), UV/Vis. spectrometries, N2 adsorption isotherm, and thermogravimetric analysis. Leaching experiments showed that the catalyst is becomes progressively more anchored to the activated support after multiple cycles of reuse
