3-Bromoflavanones (I) react with hydrazine hydrate in ethanol to produce pyrazoles (V).The same reaction mixture after 48 hr at room temperature affords pyrazoles (V) and flavones (IV).In acetic acid medium, at room temperature, the reaction products are 3-bromoflavanone hydrazones (III) and flavone azines (II).However, when the reaction mixture is heated, only flavone azines (II) are formed.
