Versuchsvorschrift

5.4 G. 3-cyanodibenzo[b,f]thiepin (0.023 mole) are dissolved in 300 cc. methylene chloride and 15.87 g. m-chlorperbenzoic acid (0.092 mole) are added in portions. The resulting solution is stirred at room temperature for one hour, then excess calcium hydroxide is added. The mixture is filtered through celite and the filtrate is stripped to dryness. The yellow solid is triturated in benzene and filtered. One obtains 5.46 g. (89%) of the sulfone, m.p. 229° C.-231° C.
