Diphenyl sulfide → HCID 21964992, compound

Participants

Reaction Steps

In 50 ml of dichloromethane were dissolved 6.07 g (0.03 mol) of diphenylsulfoxide and 11.2 g (0.06 mol) of diphenylsulfide, and 7.56 g (0.036 mol) of trifluoroacetic anhydride was poured thereinto at 0° C. Then 9.0 g (0.03 mol) of nonafluorobutanesulfonic acid was added dropwise at 0 to 5° C., followed by gradually warming to room temperature and reacting for 2 hours with stirring. After completion of the reaction, the reaction solution was washed with 100 ml of water five times and concentrated under reduced pressure, followed by purifying the resulting crude product by a column chromatography to obtain 7.85 g (Yield: 39%) of diphenyl-4-phenylthiophenylsulfonium nonafluorobutanesulfonate as a yellow oily substance.
