我们揭示了隐藏在一系列氨基有机硼（AOB）化合物背后的结构动力学，这些化合物涉及共价键、配位键和氢键的重组。通过重组两个主要结构（开放和封闭）之间的元素和键发生组合过程，这可以通过精确调节酸性或碱性条件进行化学转换。有利于开放结构的结构动力学似乎对催化更重要，如活性酰胺的甲醇分解所代表的。
We disclosed structural dynamics hidden behind a series of aminoorganoboron (AOB) compounds that involved a recombinant of covalent, dative, and hydrogen bonds. A combination process occurred via reorganizing elements and bonds between the two major structures (open and closed), which were chemically switchable through precise adjustment of either acidic or basic conditions. The structural dynamics favoring an open structure seem to be more important for catalysis, as represented by methanolysis of activated amides.
