An electrostatically directed meta borylation of sterically biased and unbiased substrates is described. The borylation follows an electrostatic interaction between the partially positive and negative charges between the ligand and substrate. With this strategy, it has been demonstrated that a wide number of challenging substrates, especially 4-substituted substrates, can selectively be borylated at
描述了空间偏压和无偏压底物的静电定向代谢硼化。硼酸化遵循配体和底物之间部分正电荷和负电荷之间的静电相互作用。使用这种策略,已经证明大量具有挑战性的底物,尤其是 4 取代底物,可以在间位选择性地硼酸化。此外,未取代的底物也表现出优异的间位选择性。该反应采用实验室稳定的配体并在较温和的温度下进行,无需合成庞大而复杂的配体/模板。
