Two series of 3-ketocoumarin dyes, the methyl-3-coumarinoylacetates and 3,3-carbonylbiscoumarins, were synthesised by condensation of salicylaldehyde derivatives with dimethyl-1,3-acetonedicarboxylate. The preparation of the corresponding cyanated derivatives of the above compounds is also reported. All compounds are characterised by their 1H-NMR and mass spectra. Electronic spectra are also recorded and discussed.
