regioselective ring-opening reaction of epoxides with various carboxylicacids under metal-free conditions is reported. The ring-opening of epoxides takes place in the presence of graphite oxide as an efficient and available catalyst to produce the corresponding 2-hydroxy monoester and 1,2-diester derivatives in good yields. Regioselective attack of the nucleophile, short reaction times, metal-free conditions
Inexpensive, non-toxic, and readily available catalyst system FeCl3/pyridine was found to be highly efficient for the opening of a wide variety of epoxides with carboxylic acid under solvent free conditions. (C) 2013 Elsevier Ltd. All rights reserved.
