Abstract
A method was developed for the production of derivatives of 4-trifluoromethyl-7-hydroxycoumarin with electron-withdrawing groups (CN, CF3CO) at position 3. The structure of 3-cyano-4-trifluoromethyl-7-acetoxycoumarin was proved by x-ray crystallographic investigation. The effect of the substituents on the geometry of the molecule is discussed.
