Synthesis of cyclic carbonates from epoxides and carbon dioxide catalyzed by an easy-to-handle ionic iron(iii) complex

Abstract

We report the successful utilization of monometallic, ionic iron(II)- and iron(III)-N2O2-ligand-systems as highly active homogeneous catalysts for the conversion of CO2 with different epoxides to cyclic carbonates. The catalytic tests were performed using propylene oxide (PO) and a range of nine substituted epoxides. Terminal monosubstituted oxides react quantitatively.

Pilot-scale synthesis of a zirconium-benzenedicarboxylate UiO-66 for CO2 adsorption and catalysis

“…200 rpm attached to the mechanical stirrer. Conversions and products were checked by GC, and only a single product of 4-phenyl-1,3-dioxolan-2-one was obtained, which was confirmed by 1 H-NMR [44]. As shown in Fig.…”

Iron Catalysis in Organic Synthesis

“…778 In the presence of neutral iron complexes as catalysts, TBAB had to be added (cf. Scheme 447) as the bromide plays the role of the nucleophile.…”

Using sustainable metals to carry out “green” transformations: Fe- and Cu-catalyzed CO2 monetization

“…The coupling between CO 2 and epoxides can be also successfully catalyzed by welldefined, iron(II) and iron(III) complexes according to a recent publication by Zevaco, Döring, and co-workers [106]. The synthesis of complexes 44 and 45 ( Figure 19) was based on a previous report by Jäger and co-workers [107][108].…”
