4-Ethoxyflavylium tetrafluoroborates with substituents in rings A and B were synthesized. Their reaction with nitrogen-containing nucleophiles was investigated. It was shown that derivatives of flavones at the carbonyl group are formed as a result of thes

Reactions of hydroxylamine with 4'-substituted flavones have been investigated.Formation of oxime flavone and isoxazole for R = -OCH3, -CH3, -Cl and only isoxazole for R = -OH has been stated, whereas for R = -NO2 formation of an intermediate product of opening γ-pyrone ring and both isomeric isoxazoles has been observed.
