Starch containing ZnO nanoparticles as a highly effective heterogeneous catalyst for the synthesis of coumarins under solvent-free conditions

Ramin Rezaei, Pejman Ghaani

Coumarins were synthesized through one-pot reactions using starch containing ZnO nanoparticles as an efficient reusable catalyst under solventfree conditions. The catalyst is inexpensive and readily available, stableand storable, easily recycled and reused for several cycles with consistent activity. The procedure offers advantages in terms of high yields, short reaction times, and mild solvent-free reaction conditions.
