Chemistry is traditionally divided into organic and inorganic chemistry. HPLC of Formula: C7H9N, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 108-47-4
Lewis acid promoted benzylic cross-couplings of pyridines with aryl bromides
Either ZnCl2, Sc(OTf)3, or BF3OEt 2 can promote the palladium-catalyzed arylation of methylpyridines and related heterocycles (see example). The complexation of the Lewis acid to the nitrogen atom in the heterocycle facilitates the reductive elimination, leading to various arylated pyridines in high yields. BF3OEt 2 was also found to promote highly regioselective metalations in the case of 2,4-lutidine. Copyright
