• Chlorofluoromethanes and sulfur hexafluoride were obtained in good yields by the electrochemical fluorination of carbon disulfide in the presence of chlorine. The yields and compositions of the products were altered by the amount of chlorine fed in during electrolysis and also by the concentration of sulfur or carbon tetrachloride dissolved in carbon disulfide. Tetrafluoromethane, trifluoromethylsulfur pentafluoride, difluoromethylene bis-(sulfur pentafluoride), bistrifluoromethyl disulfide, and chlorodifluoromethylsulfur pentafluoride were also among the products. Further, the electrochemical fluorination of elementary sulfur was accomplished by the application of the technique of chlorofluorination, and sulfur hexafluoride was obtained in a reasonable yield. The chlorofluorinations of methyl sulfide and methyl disulfide were also attempted, but they afforded only chlorotrifluoromethane in poor yields.
