Solid Trichlorotitanium (IV) Tri uoromethanesulfonate TiCl3 (OTf) Catalyzed Highly Ecient Protection of Aldeyhydes as their Acylals at Room Temperature under Solvent-Free Conditions


Department of Chemistry,Shiraz University


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.
