Abstract

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.
