|---|---|
| Friedel–Crafts acylation | Friedel–Crafts acylation is the acylation of aromatic rings with an acyl chloride using a strong Lewis acid catalyst. Friedel–Crafts acylation is also possible with acid anhydrides. |

| Pyridine | Pyridine is a basic heterocyclic organic compound with the chemical formula C5 H5 N. It is structurally related to benzene, with one methine group (=CH-) replaced by a nitrogen atom. |
What you learn in Theory:
Friedel–Crafts acylation is the acylation of aromatic rings with an acyl chloride using a strong Lewis acid catalyst. Friedel–Crafts acylation is also possible with acid anhydrides.
What you learn in Practice:
Due to the electron-withdrawing effect of the carbonyl group, the ketone product is always less reactive than the original molecule, so multiple acylations do not occur.
