In 2019,ChemistrySelect included an article by Karimi-Chayjani, Reyhaneh; Daneshvar, Nader; Tajik, Hassan; Shirini, Farhad. Electric Literature of C8H8O2. The article was titled 《Introduction of a New Magnetic Nanocatalyst as an Organic-inorganic Hybrid Framework for the Synthesis of Pyrano[2,3-d]pyrimidinone(thiones) and Pyrido[2,3-d]pyrimidines》. The information in the text is summarized as follows:
In this work, the preparation of bis-[(3-aminopropyl)triethoxysilane]dichloride immobilized on magnetic nano γ-Fe2O3@SiO2 is reported. This reagent can be obtained via the reaction of two mols. of 3-(aminopropyl)triethoxysilane with 1,4-dichlorobutane followed by immobilization of the resulted di-cationic compound on silica coated nano γ-Fe2O3. After characterization using FT-IR, XRD, FE-SEM and TGA techniques, the prepared reagent was used as a highly efficient catalyst for the promotion of the synthesis of pyrano[2,3-d]pyrimidinones(thiones) I (R = H, 2-Cl, 2-NO2, etc.; X = O, S) and pyrido[2,3-d]pyrimidine derivs II (R = H, 2-Cl, 4-F, etc.). The rates and especially the yields of the reactions were excellent in comparison to the reported catalyst for these reactions. Also, the recovery and reusability of the catalyst were excellent for both of the reactions using an external magnet.2-Methoxybenzaldehyde(cas: 135-02-4Electric Literature of C8H8O2) was used in this study.
2-Methoxybenzaldehyde(cas: 135-02-4) is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. It also has been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.Electric Literature of C8H8O2
