|---|---|
| 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:
Amines react with sulfonyl chlorides to produce sulfonamides. A typical example is the reaction of benzene sulfonyl chloride with aniline.
What you learn in Practice:
The preparation of N-acylsulfonamides is described using primary amines, arylsulfonyl chlorides and acyl chlorides.
