  刘易斯还是布朗斯特？含硼醇的萘杂环化合物的酸性和芳香性的精馏

  摘要：

  含硼杂环在从药物发现到材料科学的各种应用中都很重要；因此，为了优化这些功能，需要清楚地了解它们的结构和反应性。尽管硼酸的硼醇 (B-OH) 单元表现为路易斯酸以形成四价三羟基硼酸盐共轭碱，但有人提出假芳族半硼酸可能具有足够的芳香性以充当布朗斯台德酸并形成硼氧共轭碱，从而避免了四价硼酸阴离子会发生的环芳香性的破坏。到目前为止，还没有确凿的证据来确定共轭碱的结构和半硼“萘酚”等排体的含硼环的芳香特性。这里，这些问题通过对一系列模型苯并二氮杂硼和苯并二氮杂硼萘烷类化合物的实验、光谱、X 射线晶体学和计算研究相结合来解决。尽管这些半硼杂环明确显示在水溶液中表现为路易斯酸，但硼氮杂环衍生物具有部分芳香性，前提是它们的氮孤电子对足以参与扩展的离域化。正如动态交换和交叉实验所证明的那样，这些杂环在中性水性介质中是稳定的，并且它们的测量 p 尽管这些半硼杂环明确显示在水溶液中表现为路易斯酸，但硼氮杂环衍生

  摘要：
