In this paper, we fabricated Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub>-ABMA-MnCl<sub>2</sub> nanocomposite as a novel and recoverable nanocatalyst for the synthesis of 2,4,5-triaryl imidazoles through the three-component reaction of various derivatives of aromatic and heteroaromatic aldehydes with benzil derivatives and ammonium acetate in ethylene glycol.
