Tri Oxometallic Zeolite Composite Nanostructures: New and Efficient Catalyst for Solvent Free Synthesis of Bis (Dihydropyrimidinone) Derivatives

The facile chemical synthesis method was used for preparing Bis (dihydropyrimidinone) derivatives through Biginelli condensation reaction of terephthalic aldehyde, 1,3-dicarbonyl compounds and (thio) urea or guanidine with tri metallic Fe-Co-V/Zeolite and Fe-Co-Mo/Zeolite composite nanostructures. The structural functionalities and morphological observations of catalyst were obtained using characterization techniques of field emission scanning electron microscopy, X-ray diffraction, Fourier transfer infrared (FT-IR) spectroscopy and transmission electron microscope. The Bis (dihydropyrimidinone) derivatives confirmed by FT-IR, NMR and mass spectroscopy. Excellent yields of the biginelli products and simple work-up are attractive features of this effective protocol.
