In this project, nano-MnO2@zeolite-Y (NMOZ) was successfully prepared via hydrothermal technique and its structure was confirmed using FT-IR, XRD, FE-SEM, EDX and BET analyses. MnO2 nanoparticles stabilized on zeolite-NaY were used as nanocatalyst for efficient solventless preparation of 3,4-disubstituted isoxazole-5(4H)-one scaffolds via one-pot three-component reaction of ethyl acetoacetate, hydroxylamine hydrochloride, and aromatic aldehydes at 100 degrees C. One of the advantages of this new method is the non-use of a metal oxidant such as KMnO4 (greener method) and the stabilization of MnO2 to the zeolite-Y surface via ion bonding. This causes the MnO2 not be leached from the zeolite during the processes of nanocatalyst recycling in organic reactions. This simple approach also has promising features as like as safe, inexpensive and recyclable nanocatalyst, solvent-free reaction, short reaction times, high to excellent yields, and easy isolation of the products.
