Synthesis of Sulfenamides

Recent Literature

The copper-catalyzed coupling of diaryl disulfides with alkyl amines affords various sulfenamides in good yields. Furthermore, both aryl groups of the disulfide reacted effectively.

N-Trifluoroacetyl arenesulfenamides are effective precursors for the synthesis of unsymmetrical disulfides and sulfenamides. Reactions of N-trifluoroacetyl arenesulfenamides with thiols and amines gave the desired products in high yields within short reaction times.

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.
