Abstract
A variety of alcohols are acetylated and formylated efficiently with acetic acid and ethyl formate in the presence of catalytic amounts of Bi(III) sal ts such as BiCl3, Bi(TFA)(3) and Bi(OTf)(3), BiCl3 and Bi(OTf)(3) are also effective catalysts for acetylation of phenols. All of these catalysts are ineffective in formylation of phenols. Selective acetylation and formylatio n of alcohols in the presence of phenols is an additional advantage of this procedure.
