| 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:
Amide reduction in chemistry is the organic reduction of amides. The main reaction product in this functional group interconversion is an amine. The reagents are lithium aluminium hydride, Ether and catalytic hydrogenation (requires high temperatures and pressures).
What you learn in Practice:
N,N-disubstituted amides can be reduced to aldehydes by using an excess of the amide: R(CO)NRR' + LiAlH4 ? RCHO + HNRR' With further reduction the alcohol is obtained.
