What is Friedel-Crafts acylation with acetic anhydride?
The Friedel–Crafts acylation is the reaction of an arene with acyl chlorides or anhydrides using a strong Lewis acid catalyst. This reaction proceeds via electrophilic aromatic substitution to form monoacylated products.What is Friedel-Crafts acylation of anisole and acetic anhydride?

To do an acetylation reaction on ferrocene, acetic anhydride is used as a source of the acetyl group, and phosphoric acid is used as a catalyst which is a compound that increases the rate of the reaction but is not consumed to form an acylium ion, at the end of the reaction, acetylferrocene is produced as a major- In Friedel crafts acylation reaction, AlCl3 attacks reactant to form intermediate. AlCl3 reacts with acetyl chloride to form donor-acceptor complex. This complex then produces acyl cation (acylium ion). Then benzene ring attacks this acyl cation (acylium ion).
