• Resumen

  • Aromatic C¿H borylation of arenes and heteroarenes using stoichiometric amounts of pinacolborane was catalyzed by an iridium complex generated from ¿[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
