are versatile coupling partners in metal-catalysed cross-coupling reactions. On the other hand, their nitrogen analogues, namely, 1,3,2-benzodiazaborole-type compounds have been studied extensively for their intriguing absorption and fluorescence characteristics. Here we describe the first palladium-catalysed Suzuki-Miyaura cross-coupling reaction of easily accessible and ultra-stabilised 2-aryl-1
人们对有机硼化合物(如芳基硼酸、芳基硼酸酯和芳基三氟硼酸钾)引起了极大的兴趣,因为它们是金属催化交叉偶联反应中的通用偶联伙伴。另一方面,它们的氮类似物,即 1,3,2-苯并二氮杂硼类化合物因其有趣的吸收和荧光特性而被广泛研究。在这里,我们描述了第一个钯催化的 Suzuki-Miyaura 交叉偶联反应,该反应易于获得且超稳定的 2-芳基-1,3-二氢-1H-苯并[d]1,3,2-二氮杂硼衍生物与各种芳基溴化物. 具有吸电子性的芳基溴,
