Abstract

A commercially available Ru(II) complex catalyzes an efficient and mild reaction of thioethers with N-acyloxyamides as N-acyl nitrene precursors to provide sulfimides. If allylic sulfides are used as starting materials, a [2,3]-sigmatropic rearrangement of the sulfimide intermediate gives N-allyl-N-(thio)amides. Preliminary mechanistic studies indicated that a Ru-nitrenoid species is a key intermediate.
