Abstract Copper ferrite (CuFe2O4) nanoparticles catalyzed roomtemperaturemulticomponent reaction of aliphatic amines, formaldehyde, arylboronic acids and alkynyl carboxylic acids was reported for the synthesis of diverse propargylamines with good to excellent yields. The catalyst can be magnetically recovered and reused at least five times without significant loss of activity.

The development of a highly efficient, polystyrene-supported NHC–Ag(I) catalyst for the three-component coupling reactions of aldehydes, alkynes, and amines (A3-coupling) was described. In the presence of PS–NHC–Ag(I) (2 mol %), the A3-reactions were carried out at room temperature under solvent-free reactionconditions and the corresponding propargylamines were generated in good to excellent yields
