    • note
    • Typical experimental procedure: To the phenol (10 mmol) and β-ketoester (10 mmol), the bismuth nitrate pentahydrate (5-10 mol %) was added and the contents were stirred in a pre-heated oil-bath at 80 0C. After completion of the reaction, after the time indicated in Table 1, the reaction mixture was cooled to room temperature and the contents were poured into ice-cold water. The products were collected by filtration, washed with ice-cold water, and then recrystallized from hot ethanol to afford the coumarin derivative. All the coumarin derivatives are well-known in literature and were identified by comparison of their physical and spectral data.
