Hydroxyl-Functionalized Imidazoles: Highly Active Additives for the Potassium Iodide-Catalyzed Synthesis of 1,3-Dioxolan-2-one Derivatives from Epoxides and Carbon Dioxide was written by Werner, Thomas;Tenhumberg, Nils;Buettner, Hendrik. And the article was included in ChemCatChem in 2014.Application of 13818-44-5 This article mentions the following:
4(5)-(Hydroxymethyl)imidazole and potassium iodide were identified as an efficient catalyst system for the cycloaddition of epoxides, e.g., 1,2-butylene oxide, and carbon dioxide producing 1,3-dioxolan-2-one derivatives, e.g., 4-ethyl-1,3-dioxolan-2-one, under solvent-free conditions. The high activity of the catalyst system even at 60 °C was probably due to synergistic effects between potassium iodide and the substituted imidazole. Various functionalized and nonfunctionalized terminal epoxides as well as internal epoxides were converted into the corresponding cyclic carbonates in high yields (up to 99 %) under mild reaction conditions within a short reaction time. Compared with the previously reported amino alcs., e.g. triethanolamine based catalyzed synthesis of cyclic carbonates, the catalyst system described herein demonstrates a higher activity toward a broad substrate scope. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Application of 13818-44-5).
(2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Application of 13818-44-5
