Abstract: Reaction between CuCl2 and (Z)-2-(1-(2-(1H-benzo[d]imidazol-2- yl)ethylimino)ethyl)phenol (Hhap-aebmz) derived from o-hydroxyacetophenone (Hhap) and 2-aminoethylbenzimidazole (aebmz) gives [CuII(hap-aebmz) Cl]. Elemental analysis, magnetic susceptibility, spectral (IR and electronic) data, and single crystal X-ray studies confirm the distorted square planar structure of the complex. [CuII(hap-aebmz)Cl] has been encapsulated in the nano-cavity of zeolite-Y and its encapsulation is ensured by various physico-chemical techniques. The encapsulated complex has been used as a catalyst for oxidation of cyclohexene and phenol in the presence of H 2O2. With nearly quantitative oxidation of cyclohexene, the selectivity of the oxidation products follows the order, 2-cyclohexene-1-ol (44%)>2-cyclohexene-1-one (40%)>cyclohexeneoxide (12%)>cyclohexane-1,2- diol (4%). Oxidation of phenol (65.7%) gives catechol (66.1%)>hydroquinone (32.9%). © 2011 Taylor & Francis.
