Article

The structure of 5,6,7,8-tetrafluoro-4-hydroxycoumarin and its 3-substituted derivatives was studied by X-ray structural analysis and IR, 1H, 13C, and 15N NMR spectroscopy. It was established that the nature of the substituent at the position 3 of the coumarin ring has a significant effect on its structure.
