The synthesis of about forty new spirophosphoranes containing a PH bond offers examples of new cases of tautomeric equilibrium between the triand pentacoordinated forms as shown by: (a) recording the 31P NMR spectra between 20 and 150°, (b) using a chemical test which is specific of the PIII form. These results allowed us to discuss factors influencing the equilibrium PIII ⇌ PV.
合成约40个含PH键的新螺磷杂环戊烷提供了三配位和五配位形式之间互变异构平衡新情况的例子,如:(a)记录20至150°之间的31 P NMR光谱,(b)使用a P III形式的化学测试。这些结果让我们来讨论影响平衡P因素III ⇌P V。
