Ishiyama, Tatsuo published the artcileA stoichiometric aromatic C-H borylation catalyzed by iridium(i)/2,2′-bipyridine complexes at room temperature, Formula: C14H18BClO4, the publication is Angewandte Chemie, International Edition (2002), 41(16), 3056-3058, database is CAplus and MEDLINE.
Room-temperature C-H borylation using a stoichiometric amount of arenes and bis(pinacolato)diboron (pin2B2) is efficiently catalyzed by iridium(I) complexes generated from [{Ir(OMe)(cod)}2] (cod = 1,5-cyclooctadiene) and 4,4′-di-tert-butyl-2,2′-bipyridine (dtbpy) in hexane, and provides the corresponding arylboronates in excellent yields. Thus, [{Ir(OMe)(cod)}2]/dtbpy catalyzed C-H borylation of 1,2-dichlorobenzene with pin2B2 in hexane at 25° for 8h gave 82% 3,4-Cl2C6H3Bpin.
