  ligands for Pd-catalyzed coupling of hindered, electron-deficient anilines with hindered (hetero)aryl halides, a challenging class of C–N cross-coupling reaction with few precedents. Broad substrate scope and functional group tolerance were observed under the reaction conditions. Computational studies suggest that ligands containing phenyl substituents provide greater activity through more favorable

  由联芳基伯膦加成反式，反式衍生的联芳基膦烷配体-二亚苄基丙酮（AlisonPhos和AliPhos）形成受阻电子缺陷苯胺与受阻（杂）芳基卤化物的钯催化偶联的高活性配体，这是一类具有挑战性的C-N交叉偶联反应，几乎没有先例。在反应条件下观察到较宽的底物范围和官能团耐受性。计算研究表明，与烷基取代的膦亚胺相比，含苯基取代基的配体通过更有利的苯胺键合在催化循环中提供更大的活性。在1,1,1,1,3,3,3-六氟异丙醇（HFIP）中，通过将伯联芳基膦在1,1,1,3,3,3-六氟异丙醇（HFIP）中的磷-迈克尔加成反应，合成联芳基膦酸酯的一般和高产程序还描述了相对温和的条件（23–110°C）。

  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。
