Hydrotalcite as an efficient and reusable catalyst for acylation of phenols, amines and thiols under solvent-free conditions

Abstract

A wide variety of alcohols, phenols, amines and thiols were efficiently acylated with carboxylic acid anhydrides and chlorides in the presence of Hydrotalcite under solvent-free conditions at room temperature in good to high yields. Eco-friendly conditions and reusability of the catalyst are the most important advantages of this protocol. © 2012 Hindawi Publishing Corporation.
