| 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:
The Gabriel synthesis is named for the German chemist Siegmund Gabriel. Traditionally, it is a chemical reaction that transforms primary alkyl halides into primary amines using potassium phthalimide.
What you learn in Practice:
The utility of the method is based on the fact that the alkylation of ammonia is an unselective and inefficient route to amines in the laboratory (on an industrial scale, the alkylation of ammonia is, however, widely employed).With further reduction the alcohol is obtained.
