Advances in the catalysis of reduction of nitroaromatics and its mechanism: a tutorial review

This paper reviews the research on the conversion of nitroaromatics to aminoaromatics through catalysis. The traditional catalytic technology employs iron powder as a catalyst, which tends to generate a large amount of solid waste and water pollutants, making it the focus of research for improvement. The current research status of the catalytic reduction of nitroaromatic reactions is introduced, highlighting the main catalytic mechanism currently employed and the work conducted by our group in furthering this research. The current status and limitations of the catalytic reduction of nitroaromatic reactions are discussed. Additionally, the possibility of modulating the reaction pathway and the future development of the reaction are explored.
