  Scope of the Suzuki−Miyaura Cross-Coupling Reactions of Potassium Heteroaryltrifluoroborates

  摘要：

  A wide variety of bench-stable potassium heteroaryltrifluoroborates were prepared, and general reaction conditions were developed for their cross-coupling to aryl and heteroaryl halides. The cross-coupled products were obtained in good to excellent yields. This method represents an efficient and facile installation of heterocyclic building blocks onto preexisting organic substructures.

  activation by n-BuMgCl, this complex can catalyze the coupling of synthetically important heteroaryl pinacolborons with heteroaryl halides. Mildly basic conditions (aqueous K3PO4) allow the reaction to tolerate sensitive functional groups that were incompatible with other Ni-SMC methods. Experimental and computational studies suggest that catalyst inhibition by substitution of PPh2Me from Ni(II) intermediates

  贵金属催化剂的高成本和对环境的负面影响导致对铃木-宫浦偶联（SMC）等广泛应用的反应的非贵金属替代品的需求增加。该反应的镍催化版本未能与路易斯碱性芳基硼亲核试剂（尤其是频哪醇硼酯）实现高反应性。我们描述了 (PPh 2 Me) 2 NiCl 2的开发，作为一种廉价且空气稳定的预催化剂，可以解决这一挑战。在n -BuMgCl 的活化下，该配合物可以催化合成上重要的杂芳基频哪醇硼与杂芳基卤化物的偶联。温和的碱性条件（K 3 PO 4水溶液）允许反应耐受与其他 Ni-SMC 方法不相容的敏感官能团。实验和计算研究表明，相对于 Ni-SMC 中更常用的配体，通过路易斯碱性反应物和产物取代 Ni( II ) 中间体中的 PPh 2 Me 来抑制催化剂是不利的，这使得它能够在存在路易斯碱，例如无位阻吡啶。
