Carbon nanotube-copper ferrite-catalyzed aqueous 1,3-dipolar cycloaddition of in situ-generated organic azides with alkynes.

A novel nanohybrid catalyst was developed by assembling copper ferrite nanoparticles on carbon nanotubes. The supramolecular catalyst was applied to the one-pot azidation/1,3-dipolar cycloaddition of various substrates, at room temperature, and in an aqueous medium. The nanohybrid could also be recycled and reused by means of magnetic recovery.
