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)?

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...

Benzene underwent a Friedel-Crafts acylation reaction followed
by a Clemmensen reduction. The product gave the 1H NMR
spectrum shown above. What acyl chloride was used in the
Friedel-Crafts acylation reaction? Hint: It would be helpful
if you first assign a structure to the compound shown in the
1H NMR spectrum.

The Friedel Crafts Acylation Reaction Reaction of Anisole With Succinic Anhydride 1. Write a stepwise mechanism for this reaction. 2.(a) Starting from toluene, show how you could prepare 4-(p-tolyl) butanoic acid in two steps. (b) What would be the product of treating this acid with concentrated H2SO4? 3. What would be the main product formed in this experiment (a) if anisole were replaced with naphthalene? (b) if succinic anhydride were replaced with phthalic anhydride?

When performing a Friedel-Crafts alkylation reaction, not only does one have the problems of multiple alkylation and rearrangement of the cation, but the presence of strong electron donating groups(yes, donating is correct) prevents reaction. Provide an explanation for this. Metallocenes, like ferrocene cannot be nitrated. Why? Draw the structure of the diacetylferrocene you would obtain if ferrocene were diacetylated. Draw an arrow pushing mechanism for the formation of the acylium ion when acetic anhydride reacts with phosphoric acid. Provide the...
