Transfer hydrogenation is a crucial technology for synthesizing fine chemicals and pharmaceuticals, offering improved safety convenience over traditional hydrogen methods, although it typically requires external bases. While isopropanol commonly used as source, methanol superior but faces challenges due to its high dehydrogenation energy barrier, limiting use under mild conditions. This study focuses on investigating the differences in electrogenerated base-driven transfer of aromatic ketones solvents, using Mn(CO)₅Br cyclohexanediamine derivatives catalyst. The research demonstrates that enantiomeric excess (ee) values were obtained presence chiral Mn-based catalysts, while only racemic products observed methanol. results indicate strong dependence catalytic pathway choice solvent: isopropanol, catalyst operates via metal-ligand cooperative hydrogenation, resulting ee values, whereas methanol, occurs through metal hydride with no stereoselectivity.
