Electronic property of alkoxo‐bridged tetranuclear Fe(II) cluster and CO₂ hydrogenation reactivity

Abstract: Here we report on the synthesis of tetranuclear Fe(II) cluster [Fe4I2(O2C14H11)6] (1) derived from a benzoin‐based scaffold. The Fe centers displayed a rhombus‐like core structure, including two types of coordination environments: trigonal bipyramid and trigonal prism. The binding energy of the trigonal prismatic Fe(II) 2p electron appeared ~1.43 eV higher than that of the trigonal bipyramidal Fe(II) 2p electron because of more Fe–O bonds. The trigonal bipyramidal Fe site exhibited stoichiometric CO2 hydrogena… Show more

We used stable and nontoxic [(dimethylamino)methyl]ferrocene (Fc‐N), (hydroxymethyl)ferrocene (Fc‐O), 1,2‐bis[(dimethylamino)methyl]ferrocene (Fc‐N2), and 1‐[(dimethylamino)methyl]‐2‐(hydroxymethyl)ferrocene (Fc‐NO) as halide‐free, neutral, and bifunctional one‐component catalysts for the synthesis of cyclic carbonates. They do not need halide‐based additives or tethered salts attached to ligands when used for this coupling reaction. Among them, Fc‐N2 exhibited the best catalytic activity under the same reaction conditions. Catalytic activity decreased rapidly in the order Fc‐N2 > Fc‐NO > Fc‐N > Fc‐O, and interestingly, the more amino groups introduced into the Cp groups, the higher the activity. Various terminal and internal epoxides were easily converted into the corresponding cyclic carbonates. Calculations based on the density functional theory were also carried out to elucidate the mechanism of the coupling reaction.

Efforts are underway to develop highly active catalysts to reduce the high overpotential of the oxygen evolution reaction (OER). Metal–organic frameworks or coordination polymers are promising candidates because of their tunable structures and high surface areas. In this study, Nickel and Cobalt trans‐cinnamate (t‐ca) were synthesized via a hydrothermal method. Their structures were analyzed and found to be isostructural. Both complexes exhibited superior electrocatalytic properties in the OER compared to those of IrO2, with overpotentials of 373 and 390 mV and Tafel slopes of 58 and 66 mV/dec. These excellent characteristics were attributed to the electron delocalization of the metal centers via interactions with π‐π delocalized organic ligands. Ni t‐ca, with stronger ligand interactions, displayed an enhanced OER catalytic performance, emphasizing the importance of metal–ligand interactions and suggesting that further exploration of diverse π–π delocalized organic ligands and metal centers may lead to further advancements in electrocatalytic activity.
