Abstract: Cu(II) Complex of tetradentate Schiff‐base supported on silica [Cu(II) Schiff‐base@‐SiO2] catalyzed reactions of aryl aldehydes with carbonyl compounds (dimedon/4‐hydroxy coumarin/1,3‐cyclohexadion) and malononitrile in aqueous media (H2O:EtOH) to preparation of benzo[b]pyrans and 3,4‐dihydropyrano[c]chromanes. Also, using this… read more here.
