A simple, one pot green highly efficient condition for Pechmann condensation for synthesis of Coumarins involving grinding technic of phenols and ethyl aceto acetate under solvent free condition at room temperature catalyzed by biodegradable a versatile novel heterogeneous solid acid catalyst has been described . The remarkable features of this environmentally benign protocol are short reaction time, use of inexpensive heterogeneous catalyst and high yield of product via simple experimental procedure.
