Abstract:

5,6,7,8-Tetrafluoro-2-ethoxycarbonylchromone in aprotic polar solutions formed by nucleophilic aromatic ipso-substitution 7-alkyl(aryl)amino-5,6,8-trifluorochromones. This transformation in ethanol depended on the reactivity of the acting amine: with stronger nucleophiles, aliphatic amines, an opening of the gamma-pyrone ring occurred, with aromatic amines 7-monosubstituted chromones were the main products, and the open-chain esters formed in lesser amount.
