The relative stability of 10-hydroxy-10,9-boroxophenathrene and its electrophilic reactivity are traced through experiment and calculations to the partially aromatic character of the boron-containing heterocyclic ring. The electrophilic reactivity of 10-hydroxy-10,9-boroxophenathrene towards itself in the solid state and towards other nucleophiles in solution is described. The mechanism of the solid-state reaction has been characterised by both X-ray diffraction and thermal analysis. In solution, however, 10-hydroxy-10,9-boroxophenathrene does not react with itself, although it does react rapidly and reversibly with benzylic alcohols in solution, even at low temperatures. This selective and reversible reaction is ideal for use in self-assembly processes.
通过实验和计算,发现 10-羟基-10,9-硼氧菲的相对稳定性及其亲电反应性与含硼杂环的部分芳香特性有关。介绍了 10-羟基-10,9-硼氧菲在固态下对其本身以及在溶液中对其他亲核物的亲电反应性。固态反应的机理已通过 X 射线衍射和热分析得到表征。不过,在溶液中,10-羟基-10,9-硼氧菲不会与自身发生反应,但它在溶液中会与苯甲醇迅速发生可逆反应,即使在低温下也是如此。这种选择性和可逆性反应非常适合用于自组装过程。
