Abstract

Geminal diacetates and dipivalates were prepared in high yields through a mild and efficient reaction of aldehydes with acetic anhydride or pivalic anhydride using zirconium (IV) chloride as a catalyst under solvent free conditions. Regeneration of aldehydes from the acylals was achieved using the same catalyst in methanol.
