自从Lewis酸碱理论创建以来,如何对数量庞大而且不断增加的有机物的Lewis酸碱强度进行定量,一直是令人困挠的难题。Gutmann等人和Kainlet等人在这个方向上取得了突出进展。他们分别利用热力学方法、~(31)P-NMR和~(19)F-NMR方法测定了有限数量化合物的酸碱性,其研究结果都得到了广泛的应用。
How to quantify the Lewis acid-base strength of a large number of ever-increasing organic compounds has been a daunting problem since the Lewis acid-base theory was created. Gutmann et al. And Kainlet et al. Made outstanding progress in this direction. They used thermodynamic methods, ~ (31) P-NMR and ~ (19) F-NMR methods to determine the acidity and basicity of a limited number of compounds, respectively, and their results have been widely used.
