  摘要：

  我们报告了 1,3-二取代芳烃的间位卤化，通过使用铱催化的芳烃硼化化学形成 3,5-二取代芳基溴化物和氯化物。铱催化的芳烃与 B2pin2 发生硼化反应，然后硼酸酯与溴化铜或氯化铜 (II) 反应，将芳基硼酸酯转化为相应的芳基卤化物。各种含有烷氧基、烷基、卤素、腈、酯、酰胺和新戊酰基的芳烃和 TIPS 保护的醇以 46% 到 85% 的产率转化为相应的 3,5-二取代芳基溴化物和氯化物。此外，2,6-二取代和3-取代吡啶分别转化为4-卤代和5-卤代吡啶。

  from the olefin-bound complex observed during arene borylation to a species containing a bound heteroarene, leading to catalyst deactivation. Studies on the origins of the observed regioselectivity show that borylation occurs distal to N-H bonds due to rapid N-H borylation, creating an unfavorable steric environment for borylation adjacent to these bonds. Computational studies and mechanistic studies show

  报道了铱催化杂芳烃的 CH 硼化的研究。发现几种含有多个杂原子的杂芳烃适合由铱 (I) 前体和四甲基菲咯啉的组合催化的 CH 硼化。对反应范围的研究导致了预测硼化的区域选择性的强大规则的发展，其中最重要的是硼化发生在氮原子的远端。报告了原位形成的杂芳基硼酸酯的一锅官能化，证明了所报告的方法对合成复杂杂芳基结构的有用性。还展示了这种方法在生物活性化合物的合成和后期功能化中的应用。机理研究表明，碱性杂芳烃可以与催化剂结合，并将在芳烃硼化过程中观察到的烯烃结合复合物的静止状态改变为含有结合杂芳烃的物质，从​​而导致催化剂失活。对观察到的区域选择性起源的研究表明，由于快速的 NH 硼酸化，硼酸化发生在 NH 键的远端，为与这些键相邻的硼酸化创造了不利的空间环境。计算研究和机理研究表明，与碱性氮相邻的 CH 键缺乏可观察到的硼化并不是在 CH 活化之前与庞大的路易斯酸配位的结果，
