• What is the purpose of acetic anhydride in the acetylation of ferrocene ion?

  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).
