《Asymmetric transfer hydrogenation of ketones promoted by manganese(I) pre-catalysts supported by bidentate aminophosphines》 was published in Catalysis Communications in 2020. These research results belong to Azouzi, Karim; Bruneau-Voisine, Antoine; Vendier, Laure; Sortais, Jean-Baptiste; Bastin, Stephanie. COA of Formula: C7H7NO The article mentions the following:
A series of com. available chiral amino-phosphines, in combination with Mn(CO)5Br, was evaluated for the asym. reduction of ketones to secondary alcs. RCH(OH)R1 [R = c-hexyl, Ph, 1-naphthyl, etc.; R1 = Me, Et, i-Pr, etc.] using isopropanol as hydrogen source. With the most selective ligand, the corresponding manganese complex was synthesized and fully characterized. A series of ketones was hydrogenated in the presence of 0.5 mol% of the manganese pre-catalyst affording the chiral alcs. in high yields with enantiomeric excesses up to 99%. In the part of experimental materials, we found many familiar compounds, such as 4-Acetylpyridine(cas: 1122-54-9COA of Formula: C7H7NO)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.COA of Formula: C7H7NO
