Reaction Conditions

Reaction Steps

57.44 g of bis(4-chlorophenyl)sulfone are dissolved in 60%-oleum in a round-bottomed flask with a drying conduit under cooling with ice and stirring, heated to 120° C., and kept at this temperature overnight. The reaction mixture is added to water and the product is salted out with potassium chloride. It precipitates as a white deposit, is syphoned off, washed with a saturated potassium chloride solution, and recrystallized from ethanol/water (5:4). 65.4 g (62% yield) are obtained as product in white needles, which crumble to a white powder by drying under high vacuum at 120° C. The melting or decomposition point is above 250° C. The characterization takes place with 1H-NMR and 13C-NMR spectroscopy.
