  摘要：

  碘化铜和菲咯啉的配位体组合是高效氟化硼酸酯（芳基-Bpin）与芳基碘化物和溴化物的Suzuki-Miyaura交叉偶联的有效催化剂，可产生高至优收率的氟化联芳基。该方法是传统交叉偶联方法的理想选择，传统交叉偶联方法需要钯催化剂和化学计量的氧化银。我们注意到，在本文研究的部分氟化联芳基晶体中，π⋅⋅⋅π堆叠相互作用主导着分子堆积。它们分别存在于芳烃和全氟芳烃之间，或仅存在于芳烃或全氟芳烃之间。

• An “On-Cycle” Precatalyst Enables Room-Temperature Polyfluoroarylation Using Sensitive Boronic Acids
  作者：Liye Chen、Haydn Francis、Brad P. Carrow

  DOI：10.1021/acscatal.8b00341

  日期：2018.4.6

  fluorinated arylboronic acid building blocks in cross-coupling has remained challenging, because of their acute base sensitivity. We report a general solution to this problem using a true catalytic intermediate, Pd(PAd3)(p-FC6H4)Br, as a uniquely effective “on-cycle” precatalyst that allows Suzuki–Miyaura coupling to occur much faster than even the most severe protodeboronation side reactions. Control of boron

  交叉偶联中使用氟化芳基硼酸结构单元仍然具有挑战性，因为它们具有敏锐的碱敏感性。我们报告了使用真正的催化中间体Pd（PAd 3）（p -FC 6 H 4）Br作为唯一有效的“循环”预催化剂，可以使Suzuki-Miyaura偶联发生的速度快得多的一般解决方案。即使是最严重的原去硼副反应。还发现控制活性酸形式和休眠酯形式之间的硼形态在平衡催化速率与试剂分解之间起着至关重要的作用。该方法与任何氟化模式，对碱不稳定的官能团以及一系列溴（杂）芳烃均兼容。

  products. Here, we show that solid-state high-temperature ball-milling conditions facilitate a palladium-catalyzed cross-coupling with polyfluorinated arylboronic acids and pinacol esters employing a simple catalytic system in the absence of any stoichiometric additives. This reaction exhibits a broad substrate scope and can be carried out in air, and the use of large amounts of dry and degassed organic solvents

  多氟化芳基硼亲核试剂和芳基卤化物之间的 Suzuki-Miyaura 交叉偶联能够有效构建有机材料和催化剂中常见的多氟化结构基序。与这种转化相关的一个关键挑战涉及弱亲核多氟化有机硼试剂的缓慢金属转移，这通常会降低偶联产物的产率。在这里，我们展示了固态高温球磨条件促进了钯催化与多氟化芳基硼酸和频哪醇酯的交叉偶联，在没有任何化学计量添加剂的情况下，采用简单的催化体系。该反应底物范围广，可在空气中进行，不需要使用大量干燥脱气的有机溶剂。

  trifluoromethylation via AgI/AgIII redox shuttles are herein deciphered. This innovative cross-coupling, analogous to the CEL coupling popularized by copper, involves: i) easy AgI/AgIII 2e− oxidation; ii) phen ligation to AgIII; iii) boron-to-AgIII aryl transfer; and iv) benzotrifluoride production from aryl-AgIII intermediates. Now, AgIIICF3 chemistry is safe and reachable from AgF, KF, CF3TMS and air.
