Diphenyl Ether → 240482-96-6

Participants

Reaction Steps

In 100 ml of dichloromethane were dissolved 10.1 g (0.05 mol) of diphenylsulfoxide and 8.51 g (0.05 mol) of diphenyl ether, and 12.6 g (0.06 mol) of trifluoroacetic anhydride was added thereto at 0° C. Then 7.5 g (0.05 mol) of trifluoromethanesulfonic acid was added dropwise thereto 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 9.59 g (Yield: 38%) of diphenyl-4-phenoxyphenylsulfonium trifluoromethanesulfonate as a yellow oily substance.
