evaluated for green synthesis of 1,2,3-triazoles through the three-component reaction of various terminal alkynes with in situ generated organic azides from organic halides and epoxides in an aqueous medium that was observed to proceed well and products were obtained in good yields. In addition to showing outstanding catalytic activity, the magnetic catalyst is easy to synthesize and can be recycled
