Abstract

Iridium complexes generated from [Ir(OMe)(COD)](2) and tris[3,5-bis(trifluoromethyl)phenyl]phosphine efficiently catalyzed the ortho-C-H borylation of benzoate esters with bis(pinacolato)diboron in octane at 80 degrees C to produce the corresponding arylboronates in high yields with excellent regioselectivities.
