简介
9,9-二甲基芴-2-硼酸在常温常压下是一种白色或浅黄色固体粉末。它可溶于热乙醇中,但在水中溶解度较差。这种化合物可用作有机合成和药物化学中的中间体。
用途
作为有机合成、药物化学及材料化学的中间体,9,9-二甲基芴-2-硼酸主要通过围绕苯环上的硼酸进行转化。硼酸可以很容易地转化为各种硼酸酯等衍生物;此外,它还可以参与经典的Suzuki偶联反应以构建碳碳键、Chan-Lam偶联反应构筑碳氧键或碳氮键等。有趣的是,借助其联苯结构单元,可以通过引入该部分来有效地修饰发光材料分子并调整荧光性质。
合成方法
9,9-二甲基芴-2-硼酸的常规合成方法是从9,9-二甲基-2-溴芴开始,使用正丁基锂作为强碱去除溴原子得到相应的苯基锂试剂。随后加入硼酸三甲酯或硼酸三异丙酯,并通过酸促进硼的1,2-迁移获得产物。在此过程中,另外两个酯键也会发生水解反应,最终生成硼酸。
环境危害
9,9-二甲基芴-2-硼酸作为一种含硼有机化合物,在水中具有一定的危害性。因此,应避免未稀释或大量产品直接接触地下水、水道或污水系统。
