WebThe Friedel-Crafts alkylation reaction is important synthetically. It forms new carbon-carbon bonds, and adds alkyl groups to aromatic rings. This process involves the attack of the benzene ring with a strong electrophile. The first step of this reaction is the Lewis acid-Lewis base reaction. An alkyl halide, which is the Lewis base, and a ... WebJul 22, 2011 · Also known as: aluminum trichloride. What it’s used for: Aluminum chloride is a strong Lewis acid.It’s most commonly used as a catalyst for the halogenation (especially chlorination) of aromatic groups, as well as in the Friedel Crafts alkylation and acylation reactions. It’s also used in the Meerwein-Ponndorf-Verley reduction. Similar or equivalent …
