Reaction Steps

A three neck dry round bottom flask equipped with a condenser, argon line adapter, stir bar, and a thermometer is charged with trifluoromethane sulfonamide (8.00 g, 0.054 mole), thionyl chloride (10.12 g. 6.20 ml, 0.085 mole), and fluorosulfonic acid (5.40 g, 3.93 ml, 0.054 mole). The resulting mixture is heated with oil bath to temperature of 120° C. and is stirred for 20 h. The released HCl and SO2 gases are scrubbed with aqueous KOH solution. The obtained crude product is distilled at reduced pressure to afford CF3SO2NHSO2F in very good yield.
