Participants

Reaction Steps

Trifluoromethanesulfonic anhydride 176 microliters (1.05 mmol) was added to a solution of 300 mg (1.05 mmol) of 1-phenoxy-2-(trifluoromethylsulfinyl)benzene in 8 ml of 1,1,2-trichloro-1,2,2-trifluoroetane, and the mixture was stirred for 6 days at room temperature. The reaction solution was concentrated under reduced pressure. The residue was purified by silica gel thin-layer chromatography (acetonitrile:methylene chloride=1:3) to give 115 mg (26.2%) of S-(trifluoromethyl)dibenzo -1,4-oxathiinium trifluoromethanesulfonate as white crystals. The properties of the product are shown in Table 1.
