The Friedel-Crafts alkylation reaction proceeds via a three-step mechanism. Step 1 The Lewis acid catalyst (AlCl3) undergoes reaction with the alkyl halide, resulting in the formation of an electrophilic carbocation. Step 2 The carbocation proceeds to attack the aromatic ring, forming a cyclohexadienyl cation as an intermediate. The aromaticity of the arene is temporarily lost due to… Continue reading Mechanism

Friedel-Crafts Alkylation refers to the replacement of an aromatic proton with an alkyl group. This is done through an electrophilic attack on the aromatic ring with the help of a carbocation. The Friedel-Crafts alkylation reaction is a method of generating alkylbenzenes by using alkyl halides as reactants. The Friedel-Crafts alkylation reaction of benzene is illustrated… Continue reading Friedel-Crafts Alkylation

What is a Friedel-Crafts Reaction? A Friedel-Crafts reaction is an organic coupling reaction involving an electrophilic aromatic substitution that is used for the attachment of substituents to aromatic rings. The two primary types of Friedel-Crafts reactions are the alkylation and acylation reactions. These reactions were developed in the year 1877 by the French chemist Charles… Continue reading Friedel-Crafts Reaction
