Abstract

A ligand can make the trick: 2,2’-bipyridine was found to promote the activity of copper ferrite nanoparticles as catalysts for the azide-alkyne “click” coupling reaction. The reaction proceeded in excellent yields at room temperature, and the catalyst could be magnetically separated and recycled. Phosphorus and nitrogen containing ligands were tested and 2,2’-bipyridine proved to be the most efficient for this reaction.
