Abstract
The present article reports the synthesis of a new magnetic mesoporous nanocomposite with core–shell structure, formulated as Fe3O4@MCM‐41@ZrCl2. The prepared reagent was successfully characterized using different types of methods. The combination of unique properties of MCM‐41 as an inimitable mesoporous compound, satisfying magnetic nature of the Fe3O4magnetic nanoparticles and substantial catalytical applications of zirconium, caused the favorable efficiency of the intended nanocomposite in the synthesis of 1‐(benzothiazolylamino)phenylmethyl‐2‐naphthols via a multicomponent condensation reaction of 2‐aminobenzothiazole, 2‐naphthol, and aromatic aldehydes in absence of solvent in good to high yields (70–90%). Green conditions of the reactions, easy separation, practicability, product purity, reusability of the catalyst, affordability, and environmentally profits are the considerable advantages of this protocol.
