Magnetic copper–iron nanoparticles as simple heterogeneous catalysts for the azide–alkyne click reaction in water

The development of a novel bimetallic copper–iron nanoparticle synthesis provides a recoverable heterogeneous catalyst for the azide–alkyne “click” reaction in water. The nanoparticles catalyze the production of a diverse range of triazoles, while separation and reuse proved to be easy.
