  在简单的好氧条件下，在室温下于水中将各种芳族重氮鎓盐与ArSi（OR）3和KArBF 3进行Pd催化的交叉偶联反应，得到的产率高至优。官能团的耐受性使这些转化成为传统交叉偶联方法的诱人替代品。此外，该序列也可以在一锅多米诺骨牌过程中进行，省去了中间芳烃重氮盐的分离。

  in demand as these compounds have multiple applications in the chemical sciences and are challenging targets for metal-catalyzed cross-coupling reactions. Most approaches focus on developing new reagents as the formal nucleophilic coupling partner that can function in metal-catalyzed processes. We present an alternative approach using pyridine and diazine phosphines as nucleophilic partners and chloroazines

  需要独特的方法来合成双嗪联芳基化合物，因为这些化合物在化学科学中有多种应用，并且是金属催化交叉偶联反应的挑战性目标。大多数方法侧重于开发新试剂，作为可以在金属催化过程中发挥作用的正式亲核偶联伙伴。我们提出了一种替代方法，使用吡啶和二嗪膦作为亲核伙伴和氯嗪，其中杂联芳键是通过串联 SNAr-磷配体偶联序列形成的。杂芳基膦由氯嗪制备并且是长期稳定的固体。使用这种策略可以从丰富的氯嗪中形成一系列双嗪联芳基化合物，这对于使用传统方法来说是具有挑战性的。

  In this paper, we report the use of potassium organotrifluoroborate salts as nucleophilic organoboron reagents in the Suzuki cross-coupling reactions of 2-halo deazapurines. Regio-isomeric C-2-substituted imidazo[4,5-b]pyridine analogues were synthesized by employing this protocol in good to excellent yields. Whereas aryl and heteroaryl trifluoroborates reacted readily to give the coupled products

  在本文中，我们报告了在三卤代脱氮嘌呤的Suzuki交叉偶联反应中有机三氟硼酸钾盐作为亲核有机硼试剂的用途。通过使用该方案以良好至优异的产率合成了区域异构的C-2-取代的咪唑并[4，5- b ]吡啶类似物。芳基和杂芳基三氟硼酸酯容易反应，以高收率得到偶联产物，而三氟硼酸烷基酯则反应性较低。发现乙酸四丁铵的利用在提高交叉偶联过程的反应速率中起重要作用。另外，在硼酸和有机三氟硼酸钾盐之间进行了比较研究。

N-Methyliminodiacetyl boronates, which have been hitherto resistant to direct conversion to trifluoroborates, have been shown to undergo fluorolysis at elevated temperatures. Subsequent solvolysis of organotrifluoroborates in the presence of trimethylsilyl chloride and a wide range of bis-nucleophiles enables
