Abstract: Dried manganese dioxide (MnO2), potassium permanganate (KMnO4) and barium manganate (BaMnO4) in the presence of anhydrous aluminum and ferric chlorides performed efficient deprotection of S,S- acetals , 1,3-dithiolanes and 1,3-dithianes, in dry CH3CN at room temperature. Thioacetals derived from enolizable carbonyl compounds remained almost intact.
