CuI-Catalyzed: One-Pot Synthesis of Diaryl Disulfides from Aryl Halides and Carbon Disulfide

A new application of carbon disulfide in the presence of KF/Al2O3 is reported for the synthesis of organic symmetrical diaryl disulfides. These products were synthesized by one-pot reaction of aryl halides with the in situ generated trithiocarbonate ion in the presence of copper under air atmosphere
