| description | The production of cyclic carbonates from CO<sub>2</sub> cycloaddition to epoxides, using the C-scorpionate iron(II) complex [FeCl<sub>2</sub>{κ<sup>3</sup>-HC(pz)<sub>3</sub>}] (pz = 1<i>H</i>-pyrazol-1-yl) as a catalyst, is achieved in excellent yields (up to 98%) in a tailor-made ionic liquid (IL) medium under mild conditions (80 °C; 1–8 bar). A favorable synergistic catalytic effect was found in the [FeCl<sub>2</sub>{κ<sup>3</sup>-HC(pz)<sub>3</sub>}]/IL system. Notably, in addition to exhibiting remarkable activity, the catalyst is stable during ten consecutive cycles, the first decrease (11%) on the cyclic carbonate yield being observed during the 11th cycle. The use of C-scorpionate complexes in ionic liquids to afford cyclic carbonates is presented herein for the first time. |
