Abstract

PURPOSE: To obtain the titled compound industrially advantageously useful as a solvent and a reagent having heat stability, by oxidizing dithioacetal S-oxide with a specific amount of KMnO4.
CONSTITUTION: A dithioacetal S-oxide shown by the formula I (R1 and R2 are H, alkyl, or aryl; R3 and R4 are alkyl or aryl; two groups selected from R1WR4 can form alkylene) is reacted with 0.7W1.2mol equvalent, preferably 0.8W1.1mol equivalent of KMnO4 to give a dithioacetal S,S-dioxide. Sulfinyl group is selectively oxidized in this method, which shortens reaction time than the direct oxidation of dithioacetal and controls reaction temperature with ease.
