Copper immobilized ferromagnetic nanoparticle triazine dendrimer (FMNP@TD-Cu(II))-catalyzed regioselective synthesis of 1,4-disubstituted 1,2,3-triazoles

A copper immobilized ferromagnetic nanoparticle triazine dendrimer (FMNP@TD-Cu(II)) has been demonstrated for the first time as a recoverable and reusable heterogeneous nanocatalyst in the click synthesis of 1,4-disubstituted 1,2,3-triazoles by a one-pot three component reaction of halides, sodium azides and alkynes under mild conditions. The catalyst is very easy to handle and is environmentally safe and economical. FMNP@TD-Cu(II) was characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), FT-IR and EDX methods.
