La(OTf)۲-amine Grafted-GO as the First Multifunctional Catalyst for the One-pot Three-component Synthesis of α-Aminophosphonates

In this paper, the applicability of immobilized lanthanum (III) triflate on amine grafted graphene oxide [La(OTf)۲-amine grafted-GO] as the first multifunctional catalyst is described for the efficient synthesis of α-aminophosphonates by one-pot three-component reaction of carbonyl compounds, substituted anilines and trialkyl phosphites. Various α-aminophosphonates were synthesized in good to high yields under solvent-free conditions at room temperature. The catalyst was reused five times without significant loss of its activity.
