The Beckmann rearrangement of oximes is catalyzed by a combined use of tetrabutylammonium perrhenate (Bu4NReO4) and trifluoromethanesulfonic acid in nitromethane under azeotropic conditions, giving amides in high yield.By employing this catalytic system, amides can be prepared directly from ketones and hydroxylamine hydrochloride.
