One-Pot Synthesis of Symmetrical Diaryl Trithiocarbonates through Copper-Catalyzed Coupling of Aryl Compounds, Sodium Sulfide, and Carbon Disulfide

In this study, a protocol for the synthesis of symmetrical diaryl trithiocarbonates through the one-pot copper-catalyzed coupling reaction of sodium sulfide, carbon disulfide, and aryl compounds in DMF solution is presented. This method allows the synthesis of symmetrical diaryl trithiocarbonates without the use of highly toxic thiophosgene, and also, commercially available aryl halides were used instead of less available, toxic thiols.
