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° C to produce the corresponding arylboronates in high yields with excellent regioselectivities.
