Synthesis, absorption and fluorescence spectra as well as pKa values of 7-hydroxycoumarins with electron-withdrawing substituents in positions 3 are described. Introduction of a 4-cyano group is achieved by oxidative cyanation of coumarins using potassium cyanide and elemental bromine. 7-Hydroxycoumarins without a 4-cyano group are useful indicators for measuring physiological pH values due to their

A feasible and inexpensive reaction system for synthesis of 3-benzoxazol-2-yl-chromen-2-one as a kind of 3-heteroarylcoumarins has been developed. Both acetic acid and glycerol are simple, cheap and common chemicals, the combination of them could smoothly accelerate the three-component one-pot reaction of salicylaldehyde, o-aminophenol and ethyl cyanoacetate to yield 3-heteroarylcoumarins. This process

A convenient protocol for the synthesis of disperse yellow 184, disperse yellow 232 and their analogues via a three-component one-pot reaction of salicylaldehyde, o-aminophenol and ethyl cyanoacetate has been established. Cheap and eco-friendly ethanol was employed as solvent. One drop of low-transition-temperature mixture (LTTM) which formed from l(−)-Proline and oxalic acid could smoothly promote
