  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。
