Among different solid catalysts, supported magnetic nanoparticles (MNPs) are more interesting and widely used in organic reactions . MNPs have especially attracted great attention due to their extensive range of usages in different ﬁelds such as drug delivery , magnetic resonance imaging (MRI) , cancer treatment through hyperthermia , and absorption of heavy metals from aqueous solutions . The signiﬁcant properties of Fe O -based nanocatalysts include high stability, easy preparation, high catalyst 3 4 loading, and simple catalyst recycling. In addition, surface functionalization of MNPs is an effective way to create a link between the feature of homogeneous and heterogeneous catalysis [7, 8]. Recently, MNPs have been used as an efﬁcient heterogeneous nanocatalyst in a number of organic reactions such as Buchwald–Hartwig, Suzuki , Sonogashira–Hagihara , and Paal–Knorr [11, 12] reactions, synthesis of sulfon- amides , coupling of phenols with aryl halides , and synthesis ofa-aminonitriles and imines . Multicomponent reactions (MCRs) are regarded as economic methods
