acidic hydrolysis of α-hydroxybenzylphosphonates and a few related derivatives was monitored in order to determine the kinetics and to map the reactivity of the differently substituted phosphonates in hydrolysis. Electron-withdrawing substituents increased the rate, while electron-releasing ones slowed down the reaction. Both hydrolysis steps were characterized by pseudo-first-order rate constants. The
监测 α-羟基苄基膦酸酯和一些相关衍生物的两步酸性水解,以确定动力学并绘制不同取代的膦酸酯在水解中的反应性。吸电子取代基增加了速率,而放电子取代基减慢了反应速度。两个水解步骤都以伪一级速率常数为特征。发现第二个 POC 键的裂变是决定速率的步骤。
