摘要：
A simple and highly efficient procedure for the synthesis of 2H-chromen-2-ones via von Pechmann condensation, involving the grinding of different phenols and beta-ketoesters in the presence of silica supported sulfuric acid at room temperature, under solvent free conditions, has been described.
