Electrosynthesis 10,11-dihydrochromeno[4,3-b]chromene-6,8(7H,9H)-dione derivatives in the presence of sodium floride as an electrolyte.of

Electrochemically induced catalytic multicomponent transformation of 4-hydroxy coumarin,arylaldehyde and cyclic 1,3-dicarbonyl compounds in alcohols in an undivided cell in the presence of sodium floride as an electrolyte results in the formation of a novel series of 10,11-dihydrochromeno[4,3-b]chromene-6,8(7H,9H)-dione derivatives in high yields
