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.
