本文合成29个新的苯并二氧磷杂戊环化合物,探索了适宜的反应条件及产物的提纯方法.通过UV、IR、Raman、NMR和MS对所有化合物的结构进行了初步的解析.高分辨质谱数据表明P=S双键的硫原子与磷杂戊环上芳基氧原子在质谱中发生硫逐-硫赶异构化。
In this paper, 29 novel benzodioxaphosphenes were synthesized and the suitable reaction conditions and purification methods were explored.The structures of all the compounds were preliminary analyzed by UV, IR, Raman, NMR and MS. Resolving mass spectrometry data indicated that sulfur-sulfur-sulfur isomerisation occurs in the mass spectrum of the sulfur atom of the P = S double bond with the aryl oxygen atom of the phosphavalen ring.
