《Overcoming Electron-Withdrawing and Product-Inhibition Effects by Organocatalytic Aerobic Oxidation of Alkylpyridines and Related Alkylheteroarenes to Ketones》 was written by Wang, Hua; Liu, Jie; Qu, Jian-Ping; Kang, Yan-Biao. Formula: C7H7NO And the article was included in Journal of Organic Chemistry in 2020. The article conveys some information:
An organocatalyzed aerobic benzylic C-H oxidation of alkyl and aryl heterocycles has been developed. This transition metal-free method is able to overcome the electron-withdrawing effect as well as product-inhibition effects in heterobenzylic radical oxidation A variety of ketones bearing N-heterocyclic groups could be prepared under relatively mild conditions with moderate to high yields. The experimental process involved the reaction of 4-Acetylpyridine(cas: 1122-54-9Formula: C7H7NO)
4-Acetylpyridine(cas: 1122-54-9) 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.Formula: C7H7NO
