scope, scalability and robustness of this unconventional catalyst-free transformation, leading to functional-ized biaryls and ultimately furnishing drug-like small molecules as well as late stage derivatization of natural compounds. In addition, the observed selectivity of the oxidative coupling reaction is related to the electronic structure of the TABs through quantum-chemical calculations and experimental
我们在此报告了由三氟芳基硼酸钾的配体交换反应制备的不对称四(杂)芳基硼酸盐(TAB)的氧化电偶联促进的多功能、无过渡金属和无添加剂的(杂)芳基-芳基偶联反应。该方法利用电化学氧化的能力,补充了现有的有机硼工具箱。我们展示了这种非常规无催化剂转化的广泛范围、可扩展性和稳健性,导致功能化联芳并最终提供类药物小分子以及天然化合物的后期衍生化。此外,通过量子化学计算和实验研究,观察到的氧化偶联反应的选择性与 TAB 的电子结构有关。
