Nano Rb2HPW12O40 as an Efficient and Novel Catalyst for One-Pot Synthesis of β-amino ketones

Abstract

The aim of this research is to study Rb₂HPW₁₂O₄₀ as a green and heterogeneous catalystfor theMannich reaction.One-pot multi-component condensation of aldehyde, an amine and a ketone at ambient temperature affords the corresponding compounds using novel nano -sized Rb₂HPW₁₂O₄₀. Simple purification, short reaction time and high yield were some of advantages of this reaction. Also, the catalyst can be readily isolated. The nano catalyst Rb₂HPW₁₂O₄₀ has been characterized by Fourier transforms infrared techniques, X-ray powder diffraction and scanning electron microscope.
