Abstract
Reductive amination has been widely used for manufacturing carbon-nitrogen-containing building blocks. Despite its versatility, the need for a chemical reductant or harmful hydrogen gas has limited its further utilization in modern chemical applications. Here, we report electrochemical reductive amination (ERA) to pursue sustainable synthetic routes. Faradaic efficiencies of about 83% are achieved using Cu metal electrodes. In-depth electrokinetic studies reveal the rate-determining step and overall reaction nature of ERA. Through the experiments using deuterated solvent and additional proton sources, we scrutinize the origin of protons during the ERA. Furthermore, CW-EPR analysis captures the radical intermediate species, formed during the catalytic cycle, advancing mechanistic understanding of ERA process. © 2023 The Royal Society of Chemistry
