CeCl3·7H2O–NaI/SiO2 system promoted Beckmann rearrangement of a variety of aldoximes and ketoximes was efficiently conducted under solvent-free and microwave irradiation conditions. This protocol afforded an alternative method for the preparation of amides by Beckmann rearrangement with advantages of short reaction time, high yield, no pollution, simple operation and easy work-up.
