摘要：
16 wt % alumina supported MoO3 has been found to be an efficient catalyst for the synthesis of various substituted coumarins via Pechmann condensation. This method offers several advantages like high yields, facile recovery and reusability of the catalyst without loss in activity, nearly neutral and solvent free condition.
