<p>Aromatic sulphones (I) substd. by lower perfluoroalkyl-sulphonamido gps. (esp. by CF3SO2NH) are prepd. by reacting an approx. equimolar mixt. of a lower perfluoroalkanesulphonanilide (II) and a benzenesulphonyl chloride (III) in the presence of FeCl3 (pref. 0.3, esp. Ca. 0.25 moles), pref. in an inert solvent (esp. 1,2-dichloroethane). Pref. (II) is 2-methyl-trifluoromethanesulphonanilide and (III) is benzenesulphonyl chloride.</p> |
