2-(2-Pyridyl)benzothiazole (pbt) manganese(I) complex [(pbt)MnBr(CO)3] undergoes chem. and electrochem. reduction, giving Mn(0) dimer [(pbt)2Mn2(CO)6] and Mn(1-) complex. Manganese tricarbonyl complexes have attracted considerable attention as competent electrocatalyst for CO2 reduction owing to their unique chem. and the natural abundance of Mn. While the analogous Re complexes are well-known to activate CO2 under anhydrous conditions, most reported Mn tricarbonyl catalysts require exogenous protons. In an effort to understand the reason for the different CO2 reduction mechanisms, we investigate the reactivity of Mn(pbt)(CO)3Br, (1, where pbt = 2-(2-pyridyl)-benzothiazole) with CO2. Our combined electrochem. and spectroscopic data suggest that 1 can undergo a CO2 conversion to CO similar to Re complexes with and without the presence of a proton source, but only at potentials significantly more neg. than the second reduction Furthermore, the one- and two-electron reduced species are chem. generated and characterized by NMR, UV-vis, and IR spectroscopy. By exploring sequential chem. reduction of 1, we uncover unusual reactivity of the reduced dimeric Mn-Mn species as well as the isolation of a species capable of C-H activation. In the part of experimental materials, we found many familiar compounds, such as Bromopentacarbonylmanganese(I)(cas: 14516-54-2SDS of cas: 14516-54-2)
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.SDS of cas: 14516-54-2
