Herein, we report the iron-catalyzed borylation of aryl ethers and aryl amines via cleavage of C-O and C-N bonds. This protocol does not require the use of Grignard reagents and displays a broad substrate scope, which allows the late-stage borylation. It also provides facile access to multisubstituted arenes through C-H functionalization using 2-pyridyloxy as the directing group.
在此,我们报告了通过 C-O 和 C-N 键断裂实现的铁催化芳基醚和芳胺的硼化反应。该方案不需要使用格氏试剂,并具有广泛的底物范围,允许进行后期硼化反应。此外,该方案还通过使用 2-吡啶氧基作为导向基团,通过 C-H 官能化反应,为多取代芳烃提供了简便的合成途径。
