The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,6-Dimethyl-3,5-heptanedione( cas:18362-64-6 ) is researched.Electric Literature of C9H16O2.Tai, Akira; Kikukawa, Tadasi; Sugimura, Takasi; Inoue, Yoshihisa; Osawa, Tsutomu published the article 《Asymmetrically modified Raney nickel catalyst (MRNi). Preparation of highly active new catalyst and its applications》 about this compound( cas:18362-64-6 ) in Shokubai. Keywords: modified Raney nickel asym hydrogenation catalyst. Let’s learn more about this compound (cas:18362-64-6).
Tartaric acid-NaBr-modified Raney nickel catalyst was prepared from ultrasonicated Raney nickel catalyst. This catalyst (TA-NaBr-MRNi-U) showed high hydrogenation activity in the enantiodifferentiating hydrogenation of Me acetoacetate and its homologs, acetylacetone, and 2,6-dimethyl-3,5-heptanedione. From the hydrogenation products, optically pure 3-hydroxybutanic acid and its homologs, 2,4-pentanediol, and 2,6-dimethyl-3,5-heptanediol, were obtained in excellent yield.
When you point to this article, it is believed that you are also very interested in this compound(18362-64-6)Electric Literature of C9H16O2 and due to space limitations, I can only present the most important information.
