Application of coumarin and coumarin-3-carboxylic acid for

Both coumarin (COU) and coumarin-3-carboxylic acid (3-CCA) (Fig 1) have been used for the detection of •OH in the case of γ-radiolysis and heterogeneous photocatalysis Reaction of COU and 3-CCA with •OH produces fluorescent products (7-hydroxy-coumarin

to provide the corresponding carboxylic acid 22 The latter was converted into the acyl chloride 23 which then reacted with the appropriate metahalophenol to provide the aryl esters 24 Finally, 6-aminomethyl- (27) and 6-acetamidomethyl-substituted (28) halophenyl esters of coumarin-3-carboxylic acid were obtained according to Scheme 4

Electrochemiluminescence Study of Europium (III) Complex with

Synthesis of Eu(III) complex with coumarin-3-carbo-xylic acid The complex was synthesized by reaction of the Eu (III) salt, Eu (NO 3) , with coumarin-3-carboxylic acid (Merck, Figure 1) in a 1:2 metal to ligand molar ratio The complex was prepared by adding ethanol solution of Eu (NO 3) into ethanol solution of the ligand The reaction
