CO₂ Fixation by Copper(II) Complexes of a Terpyridinophane Aza Receptor

Abstract

CO2 is fixed by a Cu2+ complex of a macrocyclic terpyridinophane ligand forming a carbamate group. Several features of the structure mimic the enzyme rubisco.

New Materials Derived from Heterocyclic Systems

“…This feature, the formation of a carbamate from atmospheric carbon dioxide and its stabilization, has been reproduced by an artificial model (Figure 27.28) [101].…”

A Copper(II) Molecular Catalyst for Efficient and Selective Photochemical Reduction of CO2 to CO in a Water‐Containing System

“…According to previous reports, some copper complexes could separate and fix CO 2 under mild conditions . Our previous work has also shown that dinuclear copper(II) cryptate could easily take up atmospheric CO 2 and convert it into carbonate monoesters in alcohol solution .…”

Study of the Molecular Properties of Mono- and Binuclear Metal s-Indacenyl Complexes with Ir, Rh, and Re: A Theoretical Approach

“…The most important conclusion of these reports is that, for systems where the coordination of CO 2 is not reversible, the ability to transform CO 2 into other compounds depends on the extent of the charge transfer from the transition metal to CO 2 . If the metal transfers an electron, the formation of C-C bonds is possible and the rigidity of the bimetallic system seems to play an essential role in the formation of this bond [13,14]. In this sense, interestingly, one of the most innovative works in the area of CO 2 reduction reported by Angamuthu et al in 2010 consists in the synthesis of a tetranuclear complex of Cu(I) with the ligand N-(2-mercaptopropyl)-N,N-bis(2-pyridylmethyl)amine, which spontaneously and selectively captures CO 2 from the air [15].…”
