Photochemistry
Mechanism + Description
Whilst not widely utilized, photochemistry could provide a green alternative in the selective reduction of nitro compounds. Reduction occurs in the presence of a photocatalyst like TiO2
General comments
Photochemistry has the potential to be a very green technology for reduction of nitro compounds, although energy use and efficiency would need to be considered.
