Explanation:
- The Friedel-Crafts acylation reaction involves the acylation of aromatic compounds by the use of acyl halides or anhydrides in the presence of a Lewis acid catalyst such as AlCl3.
- The reaction mechanism involves the formation of an intermediate complex between the Lewis acid catalyst and the acyl halide which activates it for reaction with the benzene ring.
- The activated acyl halide acts as an electrophile and attacks the benzene ring to form an intermediate which upon protonation yields the final product.
- However, the effective electrophile in the reaction is not the acyl halide or the Lewis acid catalyst but the acylium ion (RCO+).
- This intermediate is formed by the reaction of the acyl halide with the Lewis acid catalyst and is the actual electrophile that reacts with the benzene ring.
- The acylium ion is stabilized by resonance and is a much stronger electrophile than the acyl halide.
- Thus, the effective electrophile in the Friedel-Crafts acylation reaction is the acylium ion (RCO+).
