title: Rhodium-catalyzed Beckmann rearrangement.
abstract: [figure: see text] Beckmann rearrangement of oxime is catalyzed by [RhCl(cod)]2, trifluoromethanesulfonic acid, and tris(p-tolyl)phosphine in refluxing dichloroethane, giving the corresponding amide in good yield. Product/acid ratios of 10:20 can be attained in the reaction of benzophenone oximes.
