Mechanism Friedel-Crafts acylations proceed through a four-step mechanism. Step 1 A reaction occurs between the Lewis acid catalyst (AlCl3) and the acyl halide. A complex is formed and the acyl halide loses a halide ion, forming an acylium ion which is stabilized by resonance. Step 2 The ...
Friedel鈥揅rafts acylation reactions are widely used in thenindustrial manufacture of aromatic ketones; important intermediatesnin the synthesis of many fine chemicals and pharmaceuticals.1,2nFriedel鈥揅rafts acylation reactions are the reaction between annaromatic substrate with an acyl component in the ...
