7-trioxabicyclo[2.2.2]octane (5) was obtained from phosphorus oxychloride. Benzyl chloroformate was synthesized by the reaction of benzyl alcohol and triphosgene in good yield for the first time. N-r-Butyl-N-benzoylhydrazine(II) was prepared in a new and convenivent procedure with good yield. The reaction of 5 and II proceeded smoothly in the presence of sodium carbonate and afforded the desired compound
摘要 1-Oxo-4-chlorocarbony1-1-phospha-2,6,7-trioxabicyclo[2.2.2]octane (5) 从三氯化磷中得到。苯甲醇与三光气反应首次以良好的收率合成了氯甲酸苄酯。Nr-丁基-N-苯甲酰肼(II) 是以一种新的、简便的方法制备的,产率很高。在碳酸钠存在下,5和II反应顺利进行,以良好的收率得到所需化合物13,而在三乙胺存在下,观察到丁基被消除,得到化合物12。
