- 本文报道5种新的O-(1,2,2,2-四氯)乙基-O-取代苯基硫逐磷酰肼(1)的合成,1,3,4,2-?f二唑磷杂环戊烷(2)可以通过1在Et_3N作用下分子内脱HCl制备,并对2的环化生成机理进行了讨论。 Five new - O - polyhaloalkyl - O - substituted - phenyl - hydrazinophosphorates were synthesized and characterized by spectral data. In the presence of Et3N,they are easily transferred into 1,3,4,2 - oxadiazaphospholanes. The mechanism of the cylization of 1 to 2 was discussed.
