General methods for the highly site-selective Suzuki monocoupling of 3,5-dichloropyridazines have been discovered. By changing the ligand employed, the preferred coupling site can be switched from the 3-position to the 5-position, typically considered the less reactive C–X bond. These conditions are applicable to the coupling of a wide variety of aryl-, heteroaryl-, and vinylboronic acids with high
已经发现了3,5-二氯哒嗪高度现场选择性的Suzuki单偶联的一般方法。通过改变所用的配体,可以将优选的偶联位点从3位切换到5位,通常被认为是反应性较低的C–X键。这些条件适用于多种具有高选择性的芳基-,杂芳基-和乙烯基硼酸的偶联,因此能够以模块化的方式快速构建各种不同的二芳基吡嗪类化合物阵列。
