An efficient method for the chemoselective ring-opening rearrangement of 3-aryloxaziridines by using silver triflate alone to afford nitrones, or in the presence of a simple Brønsted acid to yield amides, has been developed. Silver triflate plays an important role in both transformations. oxaziridines - rearrangement - chemoselectivity - nitrones - amides
