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.
