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Ⅰ_(1-4),7个2-硫逐1,3,2-苯并二氧磷杂戊环的五价磷化合物Ⅱ_(1-7),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Ⅱ_(1-3)化合物可能产生红移现象。Four P(Ⅲ)benzodioxaphospholes(Ⅰ_(1-4))and seven P(Ⅴ)benzodioxaphos-pholes(Ⅱ_(1-7))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 compoundsⅡ_(1-3) were observed.

关 键 词：环化合物 波谱特性 磷杂 红移现象
