有机磷化合物的结构与反应性的研究文献上已有不少报导,但早年工作仅局限于分子极性与位阻效应来探讨结构与性能的定性关系。文献上对磷(膦)酸酯的化学结构与其反应性能的定量关系研究尚少记载。本文是报导对-取代苯基膦酸酯(Ⅰ)的合成及其取代基与酯烷基性质对它们的纸上层析比移值、克分子折射度、红外光谱特征频率、路易斯碱性及水解速度的影响,并将这些化合物的性能与结构参数进行了定量关系的讨论。这些结果对阐明苯基膦酸
There are many reports on the structure and reactivity of organophosphorus compounds in literature, but the early work is confined to the molecular polarity and steric effect to explore the qualitative relationship between structure and properties. The literature on the quantitative relationship between the chemical structure of phosphorus (phosphine) ester and its reaction performance is still little documented. This paper reports the synthesis of p-substituted phenylphosphonates (I) and the effects of their substituents and ester alkyl groups on their paper chromatography, molecular refractive index, infrared spectral characteristic frequency, Lewis basicity and The rate of hydrolysis and the quantitative relationship between the properties and structural parameters of these compounds. These results illustrate the phenylphosphonic acid
