Abstract

Abstract : A new magnetic metal–organic framework nanocomposite (CoFe2 O4 /TMU‐17‐NH2 ) was prepared via an embedding approach by synthesis of the metal–organic framework crystals in the presence of magnetic cobalt ferrite nanoparticles. We demonstrated that the resulting magnetic nanocomposite can serve as a recyclable nanocatalyst for one‐pot synthesis of bis‐3, 4‐dihydropyrimidin‐2(1 H )‐one and 3, 4‐dihydropyrimidin‐2(1 H )‐one derivatives via three‐component reaction of 1, 3‐diketone, urea or thiourea and aromatic aldehyde under solvent‐free conditions. CoFe2 O4 /TMU‐17‐NH2 was characterized using various techniques. The recovery of the nanocomposite was achieved by a simple magnetic decantation and it was reused at least seven times without significant degradation in catalytic activity.
