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.
