چکیده مقاله :
From the fundamental principles and goals of green chemistry is to design environmentally friendly reactions to minimize the harm caused by the utilization of chemicals. One of the basic ways to achieve this is the use of catalysts in chemical reactions. For this reason, the design and synthesis of heterogeneous nanocatalysts, especially multi-functional ones, are these days a hot topic of researches [1]. In view of this fact, further development of research on the synthesis of zeolite-based nanocatalysts and its application in the easy preparation of N-heterocycles [2] herein, we decided to report design and manufacturing of Ni/[(MPy)+Cl-]@ZY nanoprous through loading 4-methylpyridinium chloride ionic liquid on Ni-zeolite-Y. Its structure was identified and confirmed by various analyzes including: FT-IR, FE-SEM, EDX, XRD, TGA and N2 adsorption–desorption (BET). It also used as a recoverable and multi-functional nanocatalyst for the simple and rapid synthesis of 4-arylidene-2-phenyl-5(4H) oxazolones through the one-pot reaction of hippuric acid, arylaldehydes, acetic anhydride under mild and solvent-free conditions with excellent yields.
