Electrochemical Nitro Reduction to Amines Using Pinacolborane as Reducing Agent

Abstract Nitroaromatic compounds, as hazardous industrial pollutants, have long been extensively studied for their conversion into high-value aromatic amines. However, most of these transformation reactions require either transition-metal catalysts or high-temperature conditions. Therefore, we report an electrochemical approach utilizing pinacolborane as the reducing agent for the efficient reduction of nitroaromatic compounds. The reaction is characterized by its mild conditions and simplicity of operation, and it demonstrates excellent substrate adaptability and functional group compatibility.
