borylation of aromaticethers such as anisoles is of much interest and importance, but has remained a challenge to date. We report herein the catalytic ortho-selective C–H borylation of a wide range of aromaticethers with pinacolborane (HBpin) by rare-earth metallocene complexes. This protocol offers an efficient and straightforward route for the synthesis of a variety of borylated aromaticether derivatives

Ir catalysts supported by bidentate silyl ligands that contain P- or N-donors are shown to effect ortho borylations for a range of substituted aromatics. The substrate scope is broad, and the modular ligand synthesis allows for flexible catalyst design.
