Herein, we report the iron-catalyzed borylation of arylethers 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.

Ni‐catalyzed C−O(Py) bond activation and silylation of aryl 2‐pyridyl ethers with silylzinc chlorides were carried out. This protocol allowed the 2‐pyridyloxy group to be substituted by a silyl group with short reaction times, mild reaction conditions, and good compatibility of functional groups.
