- THE REACTIONS OF CHROMONE AND 2-HYDROXYCHROMANONE WITH HYDROXYLAMINE
-
Chromone and 2-hydroxychromanone react with hydroxylamine to give several products through attack at Ca2.The aldoxime 2 is transformed to dioxime 4 or to isoxazole 3.The dioxime exists as a tautomer mixture; it reacts in several ways, giving chromoneoxime
