含磷杂环化合物研究(Ⅵ)——2-硫逐(或无取代)-2-酯基取代氧乙烯基(或肟、胺、烷硫基)1,3,2-苯并二氧磷杂戊环化合物
The Study of Heterocyclic Organophosphorus Comdpunds(Ⅵ)——Synthesis of 2-Thio(or Zero)-2-Carbalkoxy-1,3,2-Benzodioxaphospholes
【摘要】 合成了4个1,3,2-苯并二氧磷杂戊环的三价磷化合物Ⅰ1-4,7个2-硫逐1,3,2-苯并二氧磷杂戊环的五价磷化合物Ⅱ1-7,研究了其波谱特性,认为当p(Ⅲ)存在时可影响乙烯基类反应的的E、Z体比例。观察到Ⅱ1-3化合物可能产生红移现象。
【Abstract】 Four P(Ⅲ) benzodioxaphospholes (Ⅰ-4) and seven P(Ⅴ) benzodioxaphos-pholes(Ⅱ1-7) were preparaed. The spectrum characteristics were reported. It was considered that the ratio rate of the E, Z stereoisomers of ethenyl was changed with the P(Ⅲ) valent state and the red shift in IR of the compounds Ⅱ1-3 were observed
