The azide-alkyne cycloaddition by the reaction of various phenylacetylenes with a mixture of benzyl halides and NaN 3 and also three component (A(3)) coupling reaction of aldehyde, alkyne and amine catalyzed by CuFe2O4 nanoparticles under aerobic conditions led to the formation of the 1,4-disubstituted-1,2,3-triazoles and propargylamines in excellent yields. The catalyst can be recovered by applying an external magnetic field for the subsequent cycloaddition reactions and reused without any tangible loss in catalytic efficiency.
