  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。

  带有三齿钳状配体的钴配合物催化CH-H硼化反应的评价

  摘要：

  已制备了由多种中性，三齿钳状配体支撑的二氯化钴（II）配合物，并用NaBEt 3 H原位活化后，评估了两者对2-甲基呋喃，2,6-二甲基吡啶和苯的催化硼化反应HBPin和作为硼源的B 2 Pin 2（Pin =品酸）。结合HBPin和B 2 Pin 2的化学计量实验制备定义明确的有机金属化合物提供了有关催化相关物种的性质和动力学稳定性的见解。在存在足够的给电子钳子的情况下，例如与双（膦基）吡啶螯合物，优选Co（III）静止态，并且催化C–H硼化作用有效。将氧化还原活性亚基引入钳子会降低其捐赠能力，并因此降低Co（III）静止状态的可及性。在这些情况下，不寻常的混合价μ-氢化物钴配合物已经在晶体学和光谱学上得到了表征。这些研究还揭示了原位活化钴烯烃加氢硼化催化过程中形成的活性物种，并为贱金属催化的C–B键形成反应提供了重要的设计标准。

  The reactions of pyridine-N-oxides with Ph3P under the developed conditions provide an unprecedented route to (pyridine-2-yl)phosphonium salts. Upon activation with DABCO, these salts readily serve as functionalized 2-pyridyl nucleophile equivalents. This umpolung strategy allows for the selective C2 functionalization of the pyridine ring with electrophiles, avoiding the generation and use of unstable

  吡啶-N-氧化物与Ph 3 P 在已开发条件下的反应为（吡啶-2-基）鏻盐提供了前所未有的途径。用 DABCO 活化后，这些盐很容易用作功能化的 2-吡啶基亲核试剂等价物。这种 umpolung 策略允许使用亲电试剂对吡啶环进行选择性 C2 官能化，避免产生和使用不稳定的有机金属试剂。该协议在环境温度下运行并耐受敏感的官能团，从而能够合成其他具有挑战性的化合物。
