Synthesis

In a nitrogen atmosphere, 100 g (326 mmol) of 2-bromotriphenylene was dissolved in dimethylformamide(Pinacolato diboron) 99.2 (manufactured by Wako Pure Chemical Industries, Ltd.) was dissolved in 1,000 mL of dimethylformamide (DMF)G (391 mmol) and 1,1'-bis (diphenylphosphine) ferrocene) dichloropalladium (II) (1,1-Bis (diphenylphosphine) ferrocene) dichloropalladium (II)) 2.66 g (3.26 mmol) and potassium acetate 80 g (815 mmol) of potassium acetate were added and the mixture was refluxed by heating at 150 DEG C for 5 hours. After completing the reaction,Water was added to the solution, the mixture was filtered, and then dried in a vacuum oven. The thus obtained residue was purified by flash column chromatographyTo obtain 113 g (98%) of the compound I-1. HRMS (70 eV, EI +): m / z Calcd for C24H23BO2: 354.1791, found

Multiple Electrophilic C-H Borylation of Arenes Using Boron Triiodide

Electrophilic C-H borylation of arenes using boron triiodide has been developed. This reaction proceeded smoothly in the absence of additives, and the diiodoboryl group was installed at the most sterically accessible carbon, where the HOMO is localized to a certain extent. Moreover, regioselective multiple borylation of polycyclic aromatic compounds was achieved by using excess boron triiodide. The borylated intermediates were transformed into a variety of arylboron compounds such as arylboronates, boronic acids, and trifluoroborates.
