  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。

  日期：2017.9.13

  base-promoted protodeboronation of polyfluoroaryl and heteroaryl boronic acids complicates their use in Suzuki-Miyaura coupling (SMC) because a base is generally required for catalysis. We report a "cationic" SMC method using a PAd3-Pd catalyst that proceeds at rt in the absence of a base or metal mediator. A wide range of sensitive boronic acids, particularly polyfluoroaryl substrates that are poorly compatible

  多氟芳基和杂芳基硼酸的快速、碱促进的原脱硼使它们在 Suzuki-Miyaura 偶联 (SMC) 中的使用复杂化，因为催化通常需要碱。我们报告了一种使用 PAd3-Pd 催化剂的“阳离子”SMC 方法，该催化剂在没有碱或金属介体的情况下在室温下进行。各种敏感的硼酸，特别是与经典 SMC 条件相容差的多氟芳基底物，会发生干净的偶联。化学计量实验涉及有机钯阳离子的中介作用，它支持长期假定的 SMC 中金属转移的阳离子途径。

  Suzuki–Miyaura-type reactions to proceed without an exogenous base12–14. Here we use this approach to develop a nickel-catalysed coupling of aryl boronic acids with acid fluorides15–17, which are formed in situ from readily available carboxylic acids18–22. This combination of catalyst and electrophile enables a mechanistic manifold in which a ‘transmetallation-active’ aryl nickel fluoride intermediate is generated

  有机硼亲核试剂与芳基卤化物亲电子试剂的 Suzuki–Miyaura 交叉偶联是有机化学和药物化学中应用最广泛的碳-碳键形成反应之一 1,2。与这些转化相关的一个关键挑战是它们通常需要添加外源碱，其作用是使有机硼亲核试剂和金属催化剂之间发生金属转移3。这一要求限制了反应的底物范围，因为添加的碱会促进许多有机硼底物的竞争性分解 3-5。因此，相当多的研究集中在减轻碱基介导的副反应的策略上 6-12。以前的努力主要集中在设计战略性掩蔽的有机硼试剂（以减缓碱介导的分解）6-8 或开发高活性钯预催化剂（以加速与碱介导的分解途径相关的交叉偶联）10-12。一种有吸引力的替代方法涉及确定催化剂和亲电子试剂的组合，使铃木-宫浦型反应能够在没有外源碱基的情况下进行 12-14。在这里，我们使用这种方法来开发镍催化的芳基硼酸与酰基氟的偶联 15-17，后者由容易获得的羧酸原位形成 18-22。催化剂和亲电子
