• Interrogating Pd(II) Anion Metathesis Using a Bifunctional Chemical Probe: A Transmetalation Switch
  作者：John J. Molloy、Ciaran P. Seath、Matthew J. West、Calum McLaughlin、Neal J. Fazakerley、Alan R. Kennedy、David J. Nelson、Allan J. B. Watson

  Ligand metathesis of Pd(II) complexes is mechanistically essential for cross-coupling. We present a study of halide→OH anion metathesis of (Ar)PdII complexes using vinylBPin as a bifunctional chemical probe with Pd(II)-dependent cross-coupling pathways. We identify the variables that profoundly impact this event and allow control to be leveraged. This then allows control of cross-coupling pathways

  Pd(II) 配合物的配体复分解对于交叉偶联在机械上是必不可少的。我们使用vinylBPin作为具有Pd（II）依赖性交叉偶联途径的双功能化学探针，对（Ar）PdII复合物的卤化物→OH阴离子复分解进行了研究。我们确定了对这一事件产生深远影响的变量，并允许利用控制权。然后，这允许通过促进或抑制有机硼金属转移来控制交叉偶联途径，从而产生 Suzuki-Miyaura 或 Mizoroki-Heck 产品。我们展示了这种金属转移开关如何用于级联交叉偶联/Diels-Alder 反应中的合成增益，提供硼酸化或非硼酸化碳环，包括类固醇类支架。

  a NiH-catalyzed migratory defluorinative coupling between two electronically differentiated olefins. A broad range of unactivated donor olefins can be joined directly to acceptor olefins containing an electron-deficient trifluoromethyl substituent in both intra- and intermolecular fashion to form gem-difluoroalkenes. This migratory coupling shows both site- and chemoselectivity under mild conditions

  An oxidative cross-coupling reaction between activated olefins and vinyl boronate derivatives has been developed for the highly stereoselective construction of synthetically useful (E,E)-1,3-dienes. The highlight of this reaction is that exclusive stereoselectivity (only E,E-isomer) was achieved from a base-free, ligand-free, and mild catalytic condition with a less expensive [RuCl2(p-cymene)]2 catalyst

  已经开发出活化烯烃和乙烯基硼酸酯衍生物之间的氧化交叉偶联反应，以用于合成有用的（E，E）-1，3-二烯的高度立体选择性的结构。该反应的亮点在于，使用便宜的[RuCl 2（p- Cymene）] 2催化剂，可从无碱，无配体和温和的催化条件下获得独特的立体选择性（仅E，E-异构体）。

  We report an efficient approach for the direct synthesis of alkenylboronates using copper catalysis. The Cu/TEMPO catalyst system (where TEMPO = (2,2,6,6-tetramethylpiperidin-1-yl)oxyl) exhibits both excellent reactivity and selectivity for the synthesis of alkenylboronates, starting from inexpensive and abundant alkenes and pinacol diboron. This approach allows for the direct functionalization of
