hydrazine, methylhydrazine, and phenylhydrazine gave 2-hydrazinotropones, 2-(α-methylhydrazino)-tropones, and 2-(β-phenylhydrazino)tropones, respectively. All the reactions are normal substitution at C-2 position of the tropone ring. No cine reaction was observed. The reactivity of hydrazines decreases in the order: NH2NH2>CH3NHNH2>>PhNHNH2.
2-tosyloxytropones 或 2-chlorotropones 与肼、甲基肼和苯肼的反应分别产生 2-hydrazinotropones、2-(α-methylhydrazino)-tropones 和 2-(β-phenylhydrazino)tropones。所有反应都是在托酮环的 C-2 位进行正常取代。没有观察到电影反应。肼的反应性按以下顺序降低:NH2NH2>CH3NHNH2>>PhNHNH2。
