Advancement in methodologies for reduction of nitroarenes
The importance of aryl amines as raw materials for various applications has spurred extensive research in developing economic processes for the reduction of nitroarenes. Developing green methodologies is now a compelling discipline for synthetic organic chemists. The recent surge in nanochemistry has led to the development of some interesting applications in nitro reduction processes. This review discusses some recent examples of reports in this field. The different methods are classified based on the source of hydrogen utilized during reduction and the mechanism involved in the reduction process.
