Reactions of 2-alkoxy-1,3,2-oxazaphosphinanes (including 3-alkyl derivatives) with methyl and ethyl bromoacetates give two types of Arbuzov rearrangement products (cyclic and acyclic ones). The ratio between their yields is virtually independent of the nature of the substituent in position 3 of the starting reagent, being mainly determined by the nature of the substituent in the phosphorus bound alkoxy
2-烷氧基-1,3,2-氧氮杂膦(包括 3-烷基衍生物)与溴乙酸甲酯和乙酯的反应产生两种类型的 Arbuzov 重排产物(环状和非环状产物)。它们的产率之比实际上与起始试剂 3 位取代基的性质无关,主要由磷键合烷氧基中取代基的性质决定,范围为 96:4 至 2:98。 无环产物可以转换成循环的。
