Facile and Efficient Acetylation of Primary Alcohols and Phenols with
3 déc. 2013 Pyridine is a popular catalyst for the acetylation of alcohols using acetic anhydride but is toxic
Catalysis by 4-dialkylaminopyridines
The treatment of substrates such as alcohols phenols and amines with acetic anhydride (or acetyl chloride) in the presence of pyridine has provided a

An Efficient Acetylation of Primary and Secondary Aliphatic Alcohols
Aliphatic Alcohols with Acetic Anhydride in the catalysed acetylation occurs very fast and yields are higher than with acetylation in pyridine. Table 1.
