Participants

Reaction Steps

A cooled solution of 0.28 g 3-ethylidene-6-methyl-thioflavanone and 0.2 g meta-chloroperbenzoic acid in 3 ml methylene chloride is stirred at 0° C. for 5 minutes. After filtration the organic phase is washed with saturated sodium bicarbonate aqueous solution, then with water, dried over magnesium sulfate and evaporated. The crude solid is crystallized in cyclohexane. Pure 3-ethylidene-6-methyl-thioflavanone-1-oxide is obtained as yellow crystals; m.p. 151°-160° C.
