We report herein on the palladium-catalyzed direct heteroarylation of heteroarenes (e.g., pyrroles, furans, and thiophenes) in which heteroarylsulfonyl chlorides are used as coupling partners through a desulfitative cross-coupling. These C–H bond functionalizations occurred at the α-position in the case of pyrrole and furan derivatives, while in the case of thiophenes the C–H bonds at the β-position
我们在本文中报道了杂
芳烃(例如
吡咯,
呋喃和
噻吩)的
钯催化直接杂芳基化,其中杂芳基
磺酰氯通过脱
硫交叉偶联用作偶联伙伴。在
吡咯和
呋喃衍
生物的情况下,这些C–H键的官能化发生在α位,而在
噻吩的情况下,β–位的C–H键已被杂芳基化。该方法代表了杂芳基二元组的非常简单的途径。此外,杂芳基三联体的一些例子是通过重复的C–H键芳基化反应合成的。
