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

borylated arenes furnished with alkyl, alkenyl, alkynyl, aryl, and heteroaryl functional groups is developed by merging Ir-catalyzed C–H borylations (CHB) with a chemoselective palladium-catalyzed cross-coupling of triorganoindiumreagents (Sarandeses–Sestelo coupling) with aryl halides bearing a boronic ester substituent. Using triorganoindiumcross-couplingreactions to introduce unsaturated moieties
Methyl tert-butyl ether is a suitable solvent for iridium-catalyzed C-H borylation followed, in the same pot, by palladium-catalyzed Suzuki-Miyaura cross-coupling sequences, giving high yields of biaryls.

Aromatic C–H borylation of arenes and heteroarenes using stoichiometric amounts of pinacolborane was catalyzed by an iridium complex generated from ½[Ir(OMe)(COD)]2 and 4,4′-di-tert-butyl-2,2′-bipyridine at room temperature in hexane and afforded the corresponding aryl- and heteroarylboronates in high yields with excellent regioselectivities.
