Cerium(IV) Triflate‐Catalyzed Selective Gem‐diacetylation of Aldehydes with Acetic Anhydride

Abstract

It has been observed that a catalytic amount (0.1 mol%) of cerium(IV) triflate afforded geminal diacetates from aldehydes with acetic anhydride in toluene at ambient temperature. Ketones are not affected under these reaction conditions. The reaction is rapid and mild with good to high yields.
