A series of 2H-pyrano[3,2-c]chromen-5-one derivatives were synthesized and characterized. Their photochromic and redox properties were investigated by the UV-vis absorption spectroscopy. While compounds with one or two phenyl groups incorporated at the 2-

High-intensity ultrasounds have been employed in the synthesis of 4-hydroxycoumarin derivatives, using mainly water as reaction medium. Marked improvements of reaction rates, chemoselectivity and product yields have been observed on comparing sonochemical with ordinary conditions. In the alkylation of a series of allyl and benzyl bromides a pathway switch occured to yield 3-alkyl-4-hydroxycoumarin derivatives.
