AN EFFICIENT AND SIMPLE PROCEDURE FOR PREPARATION OF ESTERS AND ANHYDRIDES FROM ACID CHLORIDES IN THE PRESENCE OF 1,4-DIAZABICYCLO[2.2.2]OCTANE (DABCO) UNDER SOLVENT-FREE CONDITIONS

ABSTRACT A manipulatively one-pot and rapid method for the synthesis of aliphatic and aromatic ester and anhydride from acid chloride and alcohol or potassium salt of carboxylic acid under solvent-free conditions is reported. The reaction has been carried out in excellent yield and short reaction time in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) under solvent-free conditions.
