which easily isomerise to the phosphoramidates (3), expect in the case of the more stable bicyclic analogues, e.g., 3-(2,6-dimethylphenyl)-2,2-ethylenedioxy-2-phenyl-2,3-dihydro- 1,3,2-benzothiazaphosp(V)ole(5; Y = H), which by X-ray crystallography, is much disorted towards a square pyramid.
芳基2-硝基苯硫醚与三价磷试剂反应生成新颖的氧杂氮杂膦酸(2 ; X = S),它很容易异构化为氨基磷酸酯(3),对于更稳定的双环类似物,例如3- (2,6-二甲基苯基)-2,2-亚乙基二氧基-2-苯基-2,3-二氢-1,3,2-苯并噻唑磷(V)ole(5 ; Y = H),通过X射线晶体学分析,朝着方形金字塔变形了很多。
