quantity of aniline hydrochloride in the presence of aniline as solvent (i) Why is acetic anhydride preferred over acetyl chloride for acetylation reaction?
The optimised N-acetylation reaction was performed by adding. (1 equivalent) to the substrate aniline dissolved in different solvents. It is interesting to note
Acetylation of aniline to prepare acetanilide is part of the cur- riculum of many undergraduate organic synthesis labs. The pro- cedure is also used for the
However by protecting the –NH2 group by acetylation reaction Benzenediazonium chloride is prepared by the reaction of aniline with nitrous acid at 273-278K.
Other aromatic amines were also acetylated by using this procedure. Figure 2. Mechanism of acetylation of aniline with acetic acid-tartaric acid. Result
