Reactions of 5-cyano-1,4,6,9-trioxathia-5-phosphaspiro[4,4]nonanes with compounds containing a labile hydrogen atom
摘要:
All the investigated reactions of 5-cyano-1,4,6,9-trioxathia-5-phosphaspiro[4,4]nonanes with compounds containing a labile hydrogen atom proceed with the loss of HCN, predominant opening of the oxathiophospholane ring, and formation of 2-oxo-1,3,2-dioxaphospholane derivatives.

SN2(P) reactions of chlorophosphates, which take place with inversion of configuration, are highly dependent upon the nature of the nucleophile. On the contrary, exocyclic substitutions of five-membered ring chlorophosphates with retention show a marked kinetic levelling effect.
