and efficient method for the hydrolysis of organotrifluoroborates to unveil boronic acids using silica gel and H2O was developed. This method proved to be tolerant of a broad range of aryl-, heteroaryl-, alkenyl-, and alkyltrifluoroborates as well as structurally diverse aminomethylated organotrifluoroborates. As anticipated, electron-rich substrates provided the corresponding boronic acids more readily
开发了一种使用硅胶和 H 2 O水解有机三氟硼酸盐以揭示硼酸的通用、温和且有效的方法。事实证明,该方法可以耐受各种芳基-、杂芳基-、烯基-和烷基三氟硼酸盐以及结构多样的氨甲基化有机三氟硼酸盐。正如预期的那样,由于共振稳定的二氟硼烷中间体,富电子底物比缺电子底物更容易提供相应的硼酸。开发的方法进一步扩展用于将有机三氟硼酸盐转化为相应的硼酸酯。
