| dc.description.abstract | Yb(OTf)3 is used as an alternative to conventional acid catalysts in the Pechmann condensation reaction of phenols with β-keto esters leading to the formation of coumarin derivatives. This new method has the advantage of high yields, solvent-free conditions, short reaction times and reusability of the catalyst with no loss of yield. Ytterbium triflate catalyzed Pechmann reaction applied to synthesis of coumarin derivatives is simple and environmentally friendly process. | en_US |
