Mechanism of Friedel–Crafts alkylation.


A Friedel-Crafts reaction is a class of substitution reactions, catalyzed by acidic metal hydrides (e.g., aluminum chloride); an alkyl halide or an acid chloride reacts with an aromatic compound, the alkyl or acyl group replacing a hydrogen atom on the aromatic ring: the carbonium ion formed attacks the ring as an electrophile.
