Ishiyama, Tatsuo published the artcileOrtho-C-H borylation of benzoate esters with bis(pinacolato)diboron catalyzed by iridium-phosphine complexes, Quality Control of 1146214-86-9, the publication is Chemical Communications (Cambridge, United Kingdom) (2010), 46(1), 159-161, database is CAplus and MEDLINE.
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.
