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.
