A new, ruthenium-catalyzed method for peri C-H arylation of 1-naphthol with a variety of aryl and heteroaryl halides (iodides, bromides) is reported that overcomes the limitations of previous palladium-catalyzed approaches. Yields for the 21 examples range from 16-99%, with an average of 71%, and the reaction tolerates a variety of functional groups: pyridine, pyrimidine, primary aniline, aldehyde, and ester. In the experimental materials used by the author, we found 5-Bromo-2-chloropyridine(cas: 53939-30-3Name: 5-Bromo-2-chloropyridine)
5-Bromo-2-chloropyridine(cas: 53939-30-3) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Name: 5-Bromo-2-chloropyridine
