Abstract This paper describes the preparation of tetramethylammonium chlorochromate (TMACC) as a new and efficient reagent for the oxidative deprotection of trimethylsilyl and tetrahydropyranyl ethers or ethylene acetals and ketals to the corresponding carbonyl compounds in refluxing acetonitrile in the presence of catalytic amounts of aluminum chloride.
