A New and efficient magnetic nanocatalyst has been fabricated via covalent grafting of an aza-crown ether Cu(II) complex on silica coated iron oxide support. The above mentioned magnetic nanocatalyst has been characterized by various techniques such as SEM, TEM, XRD, FT-IR, TGA and ICP. After preparation, the applicability of this catalyst in the synthesis of triazole and tetrazole derivatives was studied. The prominent features of the present methodology are: high yields, short reaction times, easy preparation, magnetical separation and favorable recoverability of the catalyst (for at least five runs without significant loss of catalytic activity).
