Nano-Rb2HPW12O40 as an Efficient and Novel Catalyst for One-Pot Synthesis of β-Amino Ketones.

The aim of the research described was to study Rb2HPW12O40 as a green and heterogeneous catalyst for the Mannich reaction. One-pot multi-component condensation of an aldehyde, an amine and a ketone at ambient temperature affords the corresponding β-amino ketones using novel nano-sized Rb2HPW12O40. Simple purification, short reaction time and high yield are some of the advantages of this reaction.
