“…Koizumi et al. used deprotonated triethanolamine as a monodentate ligand on their Mn–bpy complexes to capture carbon dioxide [95] . The reversible insertion of CO 2 into the Mn−O bond according to the proposed mechanism (Scheme 10) occurred with an equilibrium constant >1000 and was confirmed by NMR and IR spectroscopy as well as DFT calculations.…”

Transition Metal Complexes as Catalysts for the Electroconversion of CO₂: An Organometallic Perspective

The electrocatalytic transformation of carbon dioxide has been a topic of interest in the field of CO2 utilization for a long time. Recently, the area has seen increasing dynamics as an alternative strategy to catalytic hydrogenation for CO2 reduction. While many studies focus on the direct electron transfer to the CO2 molecule at the electrode material, molecular transition metal complexes in solution offer the possibility to act as catalysts for the electron transfer. C1 compounds such as carbon monoxide, formate, and methanol are often targeted as the main products, but more elaborate transformations are also possible within the coordination sphere of the metal center. This perspective article will cover selected examples to illustrate and categorize the currently favored mechanisms for the electrochemically induced transformation of CO2 promoted by homogeneous transition metal complexes. The insights will be corroborated with the concepts and elementary steps of organometallic catalysis to derive potential strategies to broaden the molecular diversity of possible products.

“…Koizumi et al verwendeten deprotoniertes Triethanolamin als einzähnigen Liganden an ihren Mn-bpy-Komplexen, um Kohlendioxid einzufangen. [95] Die reversible Insertion von CO 2 in die Mn-O-Bindung nach dem vorgeschlagenen Mechanismus (Schema 10) erfolgt mit einer Gleichgewichtskonstante > 1000 und wurde durch NMR-und IR-Spektroskopie sowie DFT-Rechnungen bestätigt.

Übergangsmetallkomplexe als Katalysatoren für die elektrische Umwandlung von CO₂ – eine metallorganische Perspektive

2021

Die elektrokatalytische Umwandlung von Kohlendioxid ist in der CO2‐Nutzung seit langem von Interesse. Während sich viele Studien auf den direkten Elektronentransfer vom Elektrodenmaterial auf das CO2‐Molekül konzentrieren, bieten molekulare Übergangsmetallkomplexe in Lösung die Möglichkeit, als Katalysatoren für den Elektronentransfer zu wirken. C1‐Verbindungen wie Kohlenmonoxid, Formiat oder Methanol werden oft als Hauptprodukte angestrebt, aber auch kompliziertere Umwandlungen sind innerhalb der Koordinationssphäre des Metallzentrums möglich. Dieser Perspektivartikel behandelt ausgewählte Beispiele, um die gegenwärtig favorisierten Mechanismen für die elektrochemisch induzierten und durch homogene Übergangsmetallkomplexe geförderten Umwandlungspfade von CO2 zu illustrieren und zu kategorisieren. Diese Erkenntnisse werden mit den Konzepten und Elementarschritten der metallorganischen Katalyse untermauert, um mögliche Strategien zur Erweiterung der molekularen Produktvielfalt als Zukunftsperspektive abzuleiten.
