Aryl 2,2,2-trifluoroethyl sulfides were synthesized by copper(I)-catalyzed nucleophilic aromatic substitution reaction (Ullmann coupling). The method requires aryl iodides and 2,2,2-trifluoroethyl thioacetate as starting materials, benzylamine as solvent and base, and a copper(I) bromide as a catalyst. The reaction mixture was stirred at 110 °C for 6 h under inert atmosphere to afford the targeted
