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.
