Roy, Sayontani Sinha; Talukdar, Kallol; Jurss, Jonah W. published an article in 2021. The article was titled 《Electro- and Photochemical Reduction of CO2 by Molecular Manganese Catalysts: Exploring the Positional Effect of Second-Sphere Hydrogen-Bond Donors》, and you may find the article in ChemSusChem.Category: bromides-buliding-blocks The information in the text is summarized as follows:
A series of mol. Mn catalysts featuring aniline groups in the second-coordination sphere has been developed for electrochem. and photochem. CO2 reduction The arylamine moieties were installed at the 6 position of 2,2′-bipyridine (bpy) to generate a family of isomers in which the primary amine is located at the ortho- (1-Mn), meta- (2-Mn), or para-site (3-Mn) of the aniline ring. The proximity of the second-sphere functionality to the active site is a critical factor in determining catalytic performance. Catalyst 1-Mn, possessing the shortest distance between the amine and the active site, significantly outperformed the rest of the series and exhibited a 9-fold improvement in turnover frequency relative to parent catalyst Mn(bpy)(CO)3Br (901 vs. 102 s-1, resp.) at 150 mV lower overpotential. The electrocatalysts operated with high faradaic efficiencies (≥70 %) for CO evolution using trifluoroethanol as a proton source. Notably, under photocatalytic conditions, a concentration-dependent shift in product selectivity from CO (at high [catalyst]) to HCO2H (at low [catalyst]) was observed with turnover numbers up to 4760 for formic acid and high selectivities for reduced carbon products. In the experiment, the researchers used Bromopentacarbonylmanganese(I)(cas: 14516-54-2Category: bromides-buliding-blocks)
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.Category: bromides-buliding-blocks
