2,4-Dichlorophenyl trifluoromethyl sulfoxide (0.71 g, 2.7 mmol), 20 ml of Fréon 113 (stored over P2O5), predistilled benzene (0.57 g, 7.3 mmol) and then triflic anhydride (1.48 g, 5.2 mmol) are introduced into a Schlenck tube placed under an inert atmosphere. The mixture is stirred for 4 days at ambient temperature (22° C.). The purification was not yet appropriate (chromatography on silica with the pentane/ethyl acetate 30/1 mixture as eluent) and did not allow the pure product to be isolated. However, the product is obtained with a crude yield of 74%.
