Friedel-Crafts Acylation of Ferrocene "riedel-Crafts reactions are examples of electrophilic aromatic substitution reactions. The eaction involves the substitution of hydrogen on the aromatic ring system by an electrophilic arbon species forming a new carbon-carbon bond. Friedel-Crafts reactions may be used to ntroduce either an alkyl or acyl group. Ferrocene does not undergo addition reactions typical of cyclopentadiene, but undergoes Electrophilic aromatic substitution. The Friedel-Crafts acylation reaction of ferrocene involves he addition of the acylium cation to one of the carbon...

Friedel-Crafts Acylation of Ferrocene
H3PO4 DISCUSSION 1. This reaction is done with a 10-fold excess of acetic anhydride, yet the dominant product of the reaction is the mono-acylated compound. Very little 1,1'-diacetylferrocene is formed. a. Why? b. What conditions are necessary to form 1,1'-diacetylferrocene as the main product? c. Why does 1,3-diacetylferrocene not form under these conditions? 2. During workup of the product, water reacts with the excess acetic anhydride to give what side product(s)?
