Ceria-Molybdenum Mix Metal Oxide: A Mild and Efficient Recyclable Catalyst for One-Pot Synthesis of Polyhydroquinoline via Hantzsch Reaction

Abstract

In laboratory, ceria-molybdenum mix metal oxide catalyst was synthesized by using simple grinding method and characterized by FT-IR, XRD, SEM, and EDX. Catalytic activities of catalyst were testified in Hantzsch condensation reaction for the synthesis of polyhydroquinoline by using dimedone, substituted aryl aldehydes, ethylacetoacetate and ammonium acetate with high percent yield. It is an efficient catalyst for 1,4-dihydropyridines synthesis. Cerium molybdenum mix metal oxide catalyst can be re-covered and re-used. DOI: http://dx.doi.org/10.17807/orbital.v12i1.1420
