Description
Summary:In the present study, a nanomagnetic bisethylferrocene‐containing ionic liquid (IL) supported on silica‐coated Fe3O4, [Fe3O4@SiO2@{CH2}3‐Imidazolium‐Fc{H2PO4}], was designed and synthesized as a novel catalyst using a simple chemical co‐precipitation procedure. The synthesized nanoparticles were identified by using EDX, FE‐SEM, XRD, and FT‐IR techniques. The catalytic activities of the novel magnetic nanoparticle were tested in the one‐pot synthesis of hydroxycoumarin derivatives through the three‐component reaction (t‐CR) between 4‐hydroxycoumarin, various aromatic aldehydes, and secondary amines at room temperature. Based on the obtained results, the prepared nano‐catalyst has progressed through a t‐CR due to the presence of acidic and basic segments in its structure. The short reaction time, high yield, eco‐friendly properties, and easy work‐up are some of the advantages of new synthesized nanomagnetic catalysts. The easy separation of the new magnetic catalyst from the reaction mixture makes it possible to reuse it after washing and drying.
