WebLet's look at the reaction for Friedel-Crafts alkylation. So we start with our benzene ring, and to benzene we're going to add an alkyl chloride, and our catalyst is aluminum chloride. And the end result is to substitute an R group, the R group that was on the alkyl chloride, for a proton on the aromatic ring. Web17 May 2024 · The first step here is to perform a Friedel-Crafts acylation reaction between benzene and propionylchloride, perhaps catalyzed by AlCl 3. This gives us ethyl phenyl ketone. The next step is to perform a reduction of the ketone to an alkane, which (as we’ll soon see) can be performed in various ways. This gives us 1-propylbenzene.

The Friedel–Crafts reactions are a set of reactions developed by Charles Friedel and James Crafts in 1877 to attach substituents to an aromatic ring. Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution. WebThe Friedel-Crafts alkylation reaction involves the use of an alkyl halide, such as a chloromethane, and a Lewis acid catalyst, such as aluminum chloride, to introduce an alkyl group onto an aromatic ring.
