Electrocatalysis is a promising tool for using CO2 as a feedstock in the chem. industry. However, controlling the selectivity for different CO2 reduction products remains a major challenge. The authors report Mn carbonyl complexes with elaborated bipyridine or phenanthroline ligands that can reduce CO2 to either formic acid, if the ligand structure contains strategically positioned tertiary amines, or CO, if the amine groups are absent in the ligand or are placed far from the metal center. The amine-modified complexes are benchmarked to be among the most active catalysts for reducing CO2 to formic acid, with a maximum turnover frequency of up to 5500 s-1 at an overpotential of 630 mV. The conversion even works at overpotentials ≥300 mV, although through an alternative mechanism. Mechanistically, the formation of a Mn-hydride species aided by in situ protonated amine groups is a key intermediate by cyclic voltammetry, 1H NMR, DFT calculations, and IR spectroelectrochem. The experimental part of the paper was very detailed, including the reaction process of Bromopentacarbonylmanganese(I)(cas: 14516-54-2Recommanded Product: Bromopentacarbonylmanganese(I))
Bromopentacarbonylmanganese(I)(cas: 14516-54-2) has many other uses. It is used in the formation of (eta6-arene)tricarbonylmanganese(I) by reacting with arene (arene= hexamethyl benzene, 1,2,4,5-tetramethyl benzene, mesitylene, p-xylene and toluene) in the presence silver salt.Recommanded Product: Bromopentacarbonylmanganese(I)
