Starting from 2-benzoylbenzoic acid (1) and prototype hydrazine itself or some of its simple congeners produce phthalazin-1(2H)-one derivatives 2a–d. Reactions of 2 with P2S5 or POCl3 gave their thione derivatives 3a–c or the chloro derivative 4 respectively. Further reactions of phthalazines 3 and 4 with hydrazine derivatives afforded their hydrazinyl derivatives 5a–d. Compounds 5a and 5d were used
从 2-苯甲酰苯甲酸 (1) 和原型肼本身或其一些简单的同系物开始,产生 phthalazin-1(2H)-one 衍生物 2a-d。2 与 P2S5 或 POCl3 的反应分别得到它们的硫酮衍生物 3a-c 或氯衍生物 4。酞嗪 3 和 4 与肼衍生物的进一步反应得到了它们的肼基衍生物 5a-d。化合物 5a 和 5d 用作三唑基 6 和吡唑基酞嗪 7 的前体。测试了一些制备的酞嗪的抗微生物活性。
