Phosphorus-based Bifunctional Organocatalysts for the Addition of Carbon Dioxide and Epoxides was written by Werner, Thomas;Buettner, Hendrik. And the article was included in ChemSusChem in 2014.Formula: C8H10O5 This article mentions the following:
Bifunctional phosphonium salts were synthesized and employed as organocatalysts for the atom efficient synthesis of cyclic carbonates from CO2 and epoxides for the first time. These catalysts were obtained in high yields by a modular, straightforward one-step synthesis. The hydrogen-bond donating alc. function in the side chain leads to a synergistic effect accelerating the catalytic reaction. The desired cyclic carbonates are obtained in high yields and selectivity under solvent-free reaction conditions without the use of any co-catalyst. Under optimized reaction conditions various epoxides were converted to the corresponding cyclic carbonates in excellent yields. The products were obtained anal. pure after simple filtration over a silica gel pad. This protocol is even applicable for a multigram reaction scale. Moreover, the catalysts could be easily recovered and reused up to five times. In the experiment, the researchers used many compounds, for example, (2-Oxo-1,3-dioxolan-4-yl)methyl methacrylate (cas: 13818-44-5Formula: C8H10O5).
(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.Formula: C8H10O5
