Abstract:

The direction of reactions of 2-ethoxycarbonyl-5,6,7,8-tetrafluoro- and 2-carboxy-5,6,7,8-tetrafluorochromones with ammonia, methylamine, hexylamine, and aniline depends on the inductive effect of the substituent at position C-2 of the chromone and on the basicity of the amine. Nucleophilic aromatic substitution of a fluorine atom takes place in the interaction of 2-ethoxycarbonyl-5,6,7,8-tetrafluorochrome with secondary amines (morpholine, N-methylpiperazine) and ethylenediamine.
