摘要： 本文研究了2,4-二氧代-1,3,2-苯并二氮磷杂环己烷的磷氢键对β-硝基苯乙烯、丙烯酸酯、丙烯腈及二硫化碳的加成反应,共合成了18个新的加成产物.发现通过选用不同的碱或控制碱的用量.可选择性的进行加成或开环反应.由X衍射证实:在加成产物的结构中,环外P-C键构象因受磷杂环船式构象影响,以邻位交叉式(A)为主.

关键词: 加成反应, 开环反应, 构象

Abstract: The addition reaction of 1, 3,2-benzodiazaphosphorin-4(1H)-one 2 oxides with(这里有图片19891208-1197-1.gif) has been studied.The structures of the eighteen new compounds synthesized have been confirmed by elemental analysis, IR, 1H NMRand MS.The condition of the reaction and conformation of P-Cof products were discussed.It was found that when the mol ratio of sodium ethoide/ I was 1: 1, the ring of compound Iwould open and when the mol ratio was 1:5, the addition reaction with would take place.But, if sodium hydride of equal mol ratio to Iwas used as the catalyst, the addition reaction of compound I with(这里有图片19891208-1197-1.gif) would take place exclusively.

Key words: Addition reaction, Open ring, Conformation
