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<\div>
