A transition metal/ligand-free disulfuration of anilines can be performed under mild conditions and exhibits broad scope across the aniline substrate and disulfur transfer reagent classes (dithiosulfonate or tetrasulfide). This reaction can be considered as a reductive disulfuration variation of the classic Sandmeyer reaction.
