An inexpensive and easily accessible sodium trifluoromethyl sulfinate (CF3SO2Na) was employed as the trifluoromethylthio source, while anilines were used as the starting materials in a process for the synthesis of copper-promoted aryl(trifluoromethyl)sulfanes. Trifluoromethylthiolation of aromatic rings in one pot over two steps is made possible by the presence of a phosphine reducing agent. In the reaction, the copper salt promotes the conversion of trifluoromethylthio anion, and the reaction offers an effective and practical way to create derivatives of trifluoromethylthio substituted benzene.

Key words: aniline, sodium trifluoromethanesulfinate, phosphine reducing agent, trifluoromethylthiolation
