| Indigo | Indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. |
What you learn in Theory:
Aliphatic nitro compounds can be reduced to aliphatic amines using several different reagents: • Catalytic hydrogenation using platinum(IV) oxide (PtO2) or Raney nickel. • Iron metal in refluxing acetic acid. • Samarium di-iodide.
What you learn in Practice:
?,?-Unsaturated nitro compounds can be reduced to saturated amines using: • Catalytic hydrogenation over palladium-on-carbon. • Iron metal. • Lithium aluminium hydride.
