Supported gold(III) on poly(ionic liquid) coated on magnetic nanoparticles produced a highly active, stable, recoverable and high loading for the synthesis of propargylamines (A(3) coupling reaction) under green conditions. The reaction of aldehyde, secondary amine and alkyne were followed in aqueous media. The catalyst was characterized by TEM, TGA, AAS, FT-IR, XRD and EDX. A broad diversity of aldehydes, secondary amines, and alkynes, and a good to excellent yield of corresponding propargylamines were synthesized using 1.0% Au. The catalyst was easily recovered and reused 10 times without significant loss of activity.
