Iodine‐Mediated Cross‐Dehydrogenative Coupling of Heterocyclic Thiols with Amines: An Easy and Practical Formation of S−N Bond

Abstract

Abstract An efficient iodine‐mediated construction of S−N bond was developed. Such a cross‐dehydrogenative coupling of heterocyclic thiols with amines proceeded smoothly under metal‐free and base‐free conditions, and afforded a series of sulfenamides in good to excellent yields. The easily available substrates and convenient synthetic procedure illustrate potential synthetic value of this protocol for the preparation of sulfenamide related biologically or pharmaceutically active compounds.
