  使用瞬时介体对单取代苯进行对位选择性硼化

  摘要：

  在本文中，我们概念化了一种瞬时介体方法，该方法具有单取代芳族化合物的对位选择性CH功能化的能力。这种方法是通过使原位生成一个多功能锍盐的通过高度亲电phenoxathiine或噻蒽双阳离子中间体，该中间体可从其与三fluoromethanesulfonic酐亚砜很容易地生成。初步的机理研究表明，对位选择性的显着性可能与噻吩类四氢呋喃中间体的不可思议的亲电子性有关。该方法的多功能性已通过para展示-mono化各种单取代的简单芳族化合物，并结合salt盐的形成和进一步的光催化转化。

  photocatalytic procedure that enables the acylation/arylation of unfunctionalized alkyl derivatives in flow. The method exploits the ability of the decatungstate anion to act as a hydrogen atom abstractor and produce nucleophilic carbon-centered radicals that are intercepted by a nickel catalyst to ultimately forge C(sp3)−C(sp2) bonds. Owing to the intensified conditions in flow, the reaction time can be reduced

  在此，我们报告了一种光催化程序，该程序可以使未官能化的烷基衍生物在流动中酰化/芳基化。该方法利用十钨酸盐阴离子作为氢原子提取物并产生亲核碳中心自由基的能力，这些自由基被镍催化剂拦截以最终形成 C(sp 3 )-C(sp 2 ) 键。由于流动条件的强化，反应时间可以从 12-48 小时减少到仅 5-15 分钟。最后，动力学测量强调了强化条件如何不改变反应机制，而是可靠地加速整个过程。

  Site‐selective borylation of simple arenes was realized in one pot via an electrophilic thianthrenation/Pd‐catalyzed borylation sequence. The key to achieve this operatically simple process is the use of Pd catalysis, which could tolerate the solvent and acidic conditions used in the thianthrenation step. This protocol features mild conditions, broad functional group tolerance, and simple manipulations

  Herein we describe an iron-catalyzed borylation of alkenyl and aryl carbamates through the activation of a C–O bond. This protocol exhibits high efficiency, a broad substrate scope, and the late-stage borylation of biorelevant compounds, thus providing potential applications in medicinal chemistry. Moreover, this method enables orthogonal transformations of phenol derivatives and also offers good opportunities
