Cho, Jian-Yang published the artcileRemarkably selective iridium catalysts for the elaboration of aromatic C-H bonds, Name: Methyl 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate, the publication is Science (Washington, DC, United States) (2002), 295(5553), 305-308, database is CAplus and MEDLINE.

Arylboron compounds have intriguing properties and are important building blocks for chem. synthesis. A family of Ir catalysts (IndIr(COD), (η⁶-mesitylene)Ir(BPin)₃ (4; HBPin = pinacolborane)) now enables the direct synthesis of arylboron compounds from aromatic hydrocarbons and boranes under solventless conditions. For example, a 98% yield of PhBPin was obtained in 15 h at 150° from benzene and HBPin (16:1 ratio) in the presence of 4 and PMe₃. The Ir catalysts are highly selective for C-H activation and do not interfere with subsequent in situ transformations, including Pd-mediated cross-couplings with aryl halides (e.g. 80% 3,5-dichloro-3′-methylbiphenyl). By virtue of their favorable activities and exceptional selectivities, these Ir catalysts impart the synthetic versatility of arylboron reagents to C-H bonds in aromatic and heteroaromatic hydrocarbons.

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.

Lu, Xu published the artcileHydrogen Bond-Accelerated meta-Selective C-H Borylation of Aromatic Compounds and Expression of Functional Group and Substrate Specificities, Safety of Methyl 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate, the publication is ACS Catalysis (2019), 9(3), 1705-1709, database is CAplus.

Meta-selective C-H borylation of aromatic compounds was accelerated when using urea moiety-containing bipyridine-type ligands unlike in cases involving a bipyridine-type ligand without the urea moiety. The acceleration was due to the recognition and capture of the aromatic substrates by the urea moiety of the ligand by H bonding. The acceleration was further enhanced by modifying the electronic and steric properties of the ligand. The functional group and substrate specificities were also observed using the urea moiety-containing ligands.

Wu, Fengshou published the artcileRecyclable Silica-Supported Iridium Bipyridine Catalyst for Aromatic C-H Borylation, Quality Control of 408492-29-5, the publication is ACS Catalysis (2014), 4(5), 1365-1375, database is CAplus.

A mesoporous SiO₂ (SBA-15)-supported bipyridine Ir complex was prepared by grafting of bipyridine onto the SiO₂ support, followed by complexation of [Ir(I)(COD)(OMe)]₂ precursor in the presence of HBpin and cyclooctene. Structural analyses by x-ray powder diffraction, N physisorption, FTIR, and solid-state NMR spectroscopy demonstrate that the 3-dimensional, hexagonal pore structure of SBA-15 is maintained after the immobilization. In particular, as a heterogeneous catalyst, this SiO₂-supported Ir complex shows moderate to good catalytic activity in the aromatic C-H borylation of a variety of substrates. More importantly, the heterogeneous catalyst is recovered easily and reused repeatedly by simple washing without chem. treatment and exhibits good recycling performance with a modest decrease in the catalytic rate, showing good potential for increasing the overall turnover number of this synthetically useful catalyst.
