- Abstract
The current work has been explored an expeditious tactic toward one‐pot multicomponent synthesis of 1,2,4,5‐tetrasubstituted and 2,4,5‐trisubstituted imidazoles using Fe3O4@THAM‐Pd MNPs as an effective catalyst. With readily accessible benzil, ammonium acetate, anilines, and aromatic aldehydes as the simple starting materials, the condensation is run under solvent‐free conditions to afford the target products in high yields. The other salient features of the present catalytic system are a simple work‐up process, shorter reaction times, ease of preparation and handling of the catalyst, and cleaner reaction profiles. In addition, the sustainability of the methodology was checked by the investigation of the stability and reusability of the catalyst using an external magnet. The results showed that Fe3O4 @THAM‐Pd MNPs can be reused for successive five runs without an appreciable decline in catalytic efficiency.
