Abstract

TiCl3(OTf) catalyzed eciently the protection of aromatic aldehydes with acetic anhydride in
the absence of solvent at room temperature with excellent yields. By this method, aliphatic
aldehydes were also converted to their corresponding acylals, in the presence of a mixture of
acetic anhydride and acetic acid at high yields.
