Xia, Yu-Yan;Lv, Qing-Yang;Yuan, Hua;Wang, Jia-Yi published 《Selective oxidation of alcohols to nitriles with high-efficient Co-[Bmim]Br/C catalyst system》. The research results were published in《Chemical Papers》 in 2021.Category: pyridine-derivatives The article conveys some information:
An efficient method for catalyzing the ammoxidation of aromatic alcs. to aromatic nitriles was developed, in which a new heterogeneous catalyst based on transition metal elements was employed, the new catalyst was named Co-[Bmim]Br/C-700 and then characterized by X-ray photo-electronic spectroscopy, transmission electron microscope and X-ray diffraction. The reaction was carried out by two consecutive dehydrogenations under the catalysis of Co-[Bmim]Br/C-700, which catalytically oxidized the alc. to the aldehyde, and then the aldehyde was subjected to ammoxidation to the nitrile. The catalyst system was suitable for a wide range of substrates and nitriles obtained in high yields, especially, the conversion rate of benzyl alc., 4-methoxybenzyl alc., 4-chlorobenzyl alc. and 4-nitrobenzyl alc. reached 100%. The substitution of ammonia and oxygen for toxic cyanide to participate in the reaction accords with the theory of green chem. And 3-Cyanopyridine (cas: 100-54-9) was used in the research process.
3-Cyanopyridine(cas: 100-54-9) has been shown to have a number of pharmacological effects: it inhibits the production of prostaglandin E2 and nitric oxide in congestive heart failure patients; it prevents the formation of diazonium salt from benzene and nitrogen dioxide; it inhibits the growth of tumor cell lines; and it protects mice from radiation injury by scavenging reactive oxygen species.
