Metal-promoted Synthesis of Cyclic Carbonates from 1,2-diols and Carbon Dioxide
Chemical fixation of CO2 to value-added products/materials/fuel has attracted more and more attention from both academia and governmental agencies all over the worldsince CO2 is an easily available and sustainable C1 resource with the advantage of being abundant, nontoxic, nonflammable and renewable. Synthesis of organic carbonates starting from CO2 is one of the most promising methodologies an...

15 صفحه اولCatalytic Processes for Chemical Conversion of Carbon Dioxide into Cyclic Carbonates and Polycarbonates
Chemical fixation of CO2 has received much attention because CO2 is the most inexpensive and renewable carbon resource from the viewpoint of green chemistry and atom economy. The kinetic and thermodynamic stability of CO2 molecule presents significant challenges in designing efficient chemical transformations based on this potential feedstock. Currently, cyclic carbonates and polycarbonates are...
متن کاملSynthesis of cyclic carbonates from epoxides and carbon dioxide using bimetallic aluminium(salen) complexes
Over the last six years, highly active catalysts for the synthesis of cyclic carbonates from epoxides and carbon dioxide have been developed. Initial studies showed that bimetallic aluminium(salen) complexes [Al(salen)]2O formed active catalysts and kinetic studies allowed the catalytic cycle to be determined. The catalysts could be immobilized on silica, allowing them to be used in a gas phase...
متن کاملChlorine-free catalysts for green synthesis of cyclic carbonates from carbon dioxide*
This article provides an overview on recent progress in the green synthesis of cyclic carbonates (CCs) from carbon dioxide (CO2) catalyzed by chlorine-free catalysts. Special emphasis is placed on the synthetic routes and catalyst structures that govern the reactivity and selectivity.
