Abstract

Zinc dichromate trihydrate (ZnCr 2 O 7 ·3H 2 O) is an efficient reagent for the immediate deprotection of aromatic and aliphatic silyl and pyranyl ethers into their corresponding carbonyl compounds in high yields at room temperature under solvent-free conditions. [ABSTRACT FROM AUTHOR]

Abstract

Solid silica chloride/KMnO 4 system oxidizes effectively aromatic and aliphatic cyclic thioacetals (1,3-dithiolanes, 1,3-dithianes) and silyl and pyranyl ethers into their corresponding carbonyl compounds in dry CH 3 CN at room temperature in high yields. Over-oxidation of aldehydes to carboxylic acids has not been observed by this system. In the absence of silica chloride, KMnO 4 in dry CH 3 CN is an ineffective reagent for these oxidations.
