Abstract
The condensation of aldehydes or ketones with amines and alkynes in the presence of pyridine-2-carboimine copper(I) complex immobilized on Fe3O4@MCM-41 nanoparticles as a novel catalyst was described, which provides an efficient and practical route to synthesize propargylamine derivatives in the mild conditions. The prepared catalyst was characterized by XRD, SEM, EDX, TEM, VSM, UV–Vis, BET and FTIR techniques. The results have been shown a unique activity for the catalyst in the reaction even at room temperature. The nano-sized magnetic catalyst was recovered by simple separation with an external magnet and favorable reusability was observed after several cycles for recovered catalyst in the model reaction.
