A novel application of Co3O4@SiO2 nanocomposite as an efficient and robust catalyst for the preparation of some imidazolone derivatives

In the present work, a simple, green and efficient procedure for the synthesis of imidazolone derivatives is described via the reaction of oxazolones and different arylamines in the presence of Co3O4@SiO2 nanocomposite as a catalyst under solvent-free conditions at 90°C. The catalyst has been fully analyzed by FT-IR, FE-SEM, EDX, and XRD analysis. The present method offers several advantages such as high yields, short reaction times, mild reaction conditions and recoverability of the catalyst. In addition, the obtained heterocyclic compounds were analyzed by FT-IR and 1HNMR spectroscopy analysis.
