  dihaloazoles can be monoarylated at a single C−X bond with high selectivity via Suzuki coupling. By changing the palladium catalyst employed, the selectivity can be switched for some dihaloazoles, allowing for Suzuki coupling at the other, traditionally less reactive C−X bond. These conditions are applicable to coupling of a wide variety of aryl-, heteroaryl-, cyclopropyl-, and vinylboronic acids with

  各种二卤代唑可以通过Suzuki偶联在单个C-X键上以高选择性单芳基化。通过改变所用的钯催化剂，可以切换一些二卤代唑的选择性，从而使Suzuki偶联在另一个传统上反应性较小的C-X键上。这些条件适用于以高选择性偶联各种芳基，杂芳基，环丙基和乙烯基硼酸，并能够以模块化的方式快速构建各种不同的二芳基唑阵列。
