Abstract2-Alkoxy-3-alkyl-1,3,2-oxazaphosphinanes containing a sterically hindered N atom react with alkyl chloroformates according to the Arbuzov mechanism only. The ratio of the open and cyclic reaction products depends on the nature of the alkoxy group in the starting phosphinane. With a less hindered N atom, acylation at the N atom gives acyclic chloridophosphites, in addition to the Arbuzov-type
摘要 含有位阻 N 原子的 2-烷氧基-3-烷基-1,3,2-氧氮杂膦仅根据 Arbuzov 机理与氯甲酸烷基酯反应。开环和环状反应产物的比例取决于起始膦烷中烷氧基的性质。对于受阻较少的 N 原子,除了 Arbuzov 型产物外,N 原子上的酰化还产生无环亚磷酸氯酯。氯化亚磷酸酯的结构通过它们向稳定硫代磷酸盐的化学转化得到证实。获得了磷酰甲酰胺和磷酰甲酰肼的氧氮杂膦类似物。
