Friedel-Crafts alkylation
Friedel-Crafts alkylation
Formula
C₆H₆ + RCl →[AlCl₃] C₆H₅R + HCl
Real World
Ethylbenzene, made by Friedel-Crafts alkylation at INEOS chemical plants, is dehydrogenated to produce styrene — the monomer for polystyrene packaging used by companies like Dart Container.
Exam Focus
State that AlCl₃ is a halogen carrier generating the carbocation electrophile R⁺, not simply a 'catalyst'.
