| Popis: | A soluble ferrate salt was synthetized by treating a novel protonated pyridine-containing macrocyclic ligand with iron(III) bromide. Its good activity as a stand-alone catalyst in CO2 cycloaddition reactions to epoxides was assessed. Good yields of cyclic organic carbonates were obtained, especially with terminal epoxides, under solvent-free reaction conditions (T = 100 °C, P (CO2) = 0.8 MPa), without the need of any Lewis base as the co-catalyst. This system proved to be active and selective towards the cyclic carbonates formation, with a broad reaction scope. A scale-up reaction on 2.5 mL of propylene oxide was performed and the robustness of the catalyst was proved up to three recycles (TON = 1020). |
