A Stoichiometric Aromatic CH Borylation Catalyzed by Iridium(I)/2,2′-Bipyridine Complexes at Room Temperature

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 correspond...

Summary: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 [Eq. (1)].
