| | Diphenyl(trifluoromethyl)sulfonium trifluoromethanesulfonate Usage And Synthesis |
| Uses | Diphenyl(trifluoromethyl)sulfonium trifluoromethanesulfonate can be used as a raw material for organic synthesis with styrene derivatives to synthesise 2-arylazo pyridine at low temperature[1]. | | Synthesis | Diphenyl(trifluoromethyl)sulfonium trifluoromethanesulfonate is synthesised using phenyl trifluoromethyl sulfoxide as a raw material by chemical reaction. The specific synthesis steps are as follows:
Trifluoromethyl sulfoxide (0.4 g, 2.1 mmol) and then benzene (4.9 g, 64 mmol) are introduced, under an inert atmosphere and at approximately 0° C. (lower limit below which benzene crystallizes), into a Schlenck tube purged beforehand with argon. Five equivalents of triflic anhydride (2.82 g, 10 mmol) are gradually added. The mixture is stirred for 1 h at 0° C. and then for 24 h at ambient temperature. The medium is evaporated and the residue is purified by chromatography with the CH3CN/CH2Cl2 (1/4) mixture as eluent. White crystals (Diphenyl(trifluoromethyl)sulfonium trifluoromethanesulfonate), having a melting point of 69-70° C., are obtained with a yield of 40%.
