Facile AlCl3-Promoted Catalytic Beckmann Rearrangement of Ketoximes.

[image omitted] Aluminum chloride, an inexpensive and commercially available Lewis acid traditionally employed for Beckmann rearrangement with stoichiometric amounts, has been now found to smoothly promote the Beckmann rearrangement of various ketoximes to the corresponding amides (up to 99% of yield) with 10 mol% catalyst loading in anhydrous acetonitrile under reflux temperature.
