Versuchsvorschrift

To an aqueous solution of ammonium chloride was added dropwise an acetone solution of pentafluorobenzenesulfonyl chloride at room temperature. During addition, pH was adjusted to 7 by an aqueous sodium hydroxide solution. Precipitated product was filtered and recrystallized from toluene to give pentafluorobenzenesulfonamide. The structure was confirmed by 1H-NMR, 19F-NMR and IR.
