A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4418-26-2, Name is Sodium 3-acetyl-6-methyl-2,4-dioxo-3,4-dihydro-2H-pyran-3-ide, molecular formula is C8H7NaO4. In an article, author is Astaneh, H. R. Haghjoo,once mentioned of 4418-26-2, SDS of cas: 4418-26-2.
Use of nanocrystalline ZnO as an efficient and reusable catalyst for a one-pot, three-component synthesis of 6-chloro- and 5,7-dichloro-4-hydroxy-3-[aryl (piperidin-1-yl)methyl]quinolin-2(1H)-ones in water
A one-pot, green, efficient and facile procedure was applied for the preparation of a series of 4-hydroxy-3-[aryl(piperidin-1-yl)methyl]quinolin-2(1H)-ones via the reaction of 6-chloro-4-hydroxyquinoline-2(1H)-one 1 and/or 5,7-dichloro-4-hydroxyquinoline-2(1H)-one 2, piperidine and aromatic aldehydes in water in the presence of nanocrystalline ZnO under reflux conditions. The desired products were obtained in satisfactory yields. The nanocrystalline ZnO can be separated and reused at least up to three times with almost the same catalytic activity.
