In this study, we document the use of a reusable magnetic nanoparticle (MNP)-supported copper catalyst for the efficient synthesis of propargylamines via the A 3 coupling of benzaldehydes, phenylacetylene, and piperidine or morpholine. The new MNPs were characterized by scanning electron microscopy, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, thermogravimetric analysis, and vibrating sample magnetometry. Notably, the activity and leaching test of the catalyst indicated that the MNPs could be reused without loss to its catalytic activity or leaching of its copper ligands.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
