Room temperature multicomponent synthesis of diverse propargylamines using magnetic CuFe2O4 nanoparticle as an efficient and reusable catalyst

Abstract

Copper ferrite (CuFe2O4) nanoparticles catalyzed room temperature multicomponent 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.
