Esterification

Cobalt(II)-Catalyzed Direct Acetylation of Alcohols with Acetic Acid. — The use
CoCl2 as recyclable catalyst is demonstrated for the direct acylation of a wide variety
27- 061 of
of alcohols using AcOH only as the acetyl source. Optically active alcohols do not undergo racemization. The reactivity of primary alcohols is higher compared to secondary
alcohols, whereas tBuOH and phenol fail to give acetylated products. All hydroxy
groups of polyols are acetylated. The reaction conditions are suitable for the esterification of alcohols (I) and (IV) with other carboxylic acids. — (VELUSAMY, S.;
