Abstract

Unsaturated 16-electron iridium and rhodium complexes bearing a silyl-bipyridine-based SiNN-pincer ligand (Bpy^SiNN) were synthesised and characterised by X-ray crystallography and NMR spectroscopy. The iridium-Bpy^SiNN complex facilitated the catalytic C(sp²)-H borylation of arenes to give arylboronate esters in high yields (≥93%) under mild conditions (∼40 °C).
