La(OTf)2-amine Grafted-GO as the First Multifunctional Catalyst for the One-pot Three-component Synthesis of α-Aminophosphonates
نویسندگان
چکیده مقاله:
In this paper, the applicability of immobilized lanthanum (III) triflate on amine grafted graphene oxide [La(OTf)2-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.

H6P2W18O62: A Green and Reusable Catalyst for the One-pot Three-Component Synthesis of Spirooxindoles in Water
Wells–Dawson tungsten heteropolyacid (H6P2W18O62) has been applied as an effective heterogeneous catalyst for one-pot synthesis of spiro[4H-pyran-3,3’-oxindoles] via reaction of various isatins, malonitrile and 1,3-dicarbonyl compound in water. The corresponding products were obtained in high yields. The catalysts were easily recycled and reused without loss of their catalytic activity.
