Reaction Steps
3-Carboxythianthrene-5,5-dioxide ((60 mg), acetic acid acid (2.0 ml) and 30% hydrogen peroxide (0.10 ml) were boiled under reflux for 10 mins., filtered and allowed to stand overnight at 0° C. 3-Carboxythianthrene-5,5,10-trioxide crystallised out, was filtered off and dried at 156° C. at 2mm. Hg, m.p. 340°-343° C.
