Ohishi, Takeshi published the artcileCarboxylation of organoboronic esters catalyzed by N-heterocyclic carbene copper(I) complexes, Synthetic Route of 214360-44-8, the publication is Angewandte Chemie, International Edition (2008), 47(31), 5792-5795, database is CAplus and MEDLINE.
N-heterocyclic carbene copper(I) complexes serve as excellent catalysts for the carboxylation of aryl- and alkenylboronic esters with CO2, affording a variety of functionalized carboxylic acid derivatives Important active intermediates such as the copper(I) aryl and carboxylate complexes, [(IPr)CuR] and [(IPr)CuOCOR] (R = 4-MeOC6H4, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), are isolated and structurally characterized.
