A novel protocol for the copper‐catalysed S‐arylation of thiophenol derivatives with aryl halides leading to diaryl sulfides is reported. The reactions were catalysed by a combination of a copper salt and a 1,2‐diamine derivative (acting both as the ligand and as the base) using exclusively water as the solvent. The recovery and successful reutilisation of the aqueous medium containing the active catalyst is described. Furthermore, one example of a “one‐pot” process involving Br/I exchange of an aryl bromide and further S ‐ arylation is presented.
