promise in catalysis due to their very high electron-donating property. In this communication double N,B-type boryl anions were designed as bidentate ligands to promote an sp(2) C-H borylation reaction. A symmetric pyridine-containing tetraaminodiborane(4) compound (1) was readily prepared as the ligand precursor that could be used, in combination with [Ir(OMe)(COD)]2, to in situ generate a highly active
