ortho-Benzoylation of phenols with aryl aldehydes to afford the substituted 2-hydroxybenzophenones can be catalyzed efficiently by Fe3O 4 nanoparticles under ligand-free conditions. This method is useful for the preparation of xanthones in good yields. The catalyst can be magnetically removed and recycled easily over four cycles without a significant decrease in activity. The applicability of magnetically retrievable Fe 3O4 nanoparticles in the oxidative coupling of aryl aldehydes with phenols under ligand free conditions is demonstrated.
