What is it about?
Heterogeneous magnetic nanocatalyst, Fe3O4@SiO2–Ligand–Cu (II) MNPs, reveals high catalytic performance within the synthesis of propargylamines using the multicomponent coupling reaction of aldehydes, phenylacetylene and secondary amines in water. To study the stability and actual structure of birhodanine derivative–copper (II) complex, DFT calculations were also performed.

Why is it important?
The nanocatalyst can be reused 10 times without loss of catalytic activity and with negligible metal leaching. Other advantages of this methodology are as follows: the employment of water as a green solvent rather than expensive, toxic and harmful organic solvents, excellent yields and general in scope. DFT calculations have confirmed the stability of the complex and the metal binding ligand.
