#6 FRIEDEL-CRAFTS ACYLATION OF FERROCENE 2. 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?

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...

Please help me solve this and show the full calculations. Calculate the limiting reactant, theoretical yield, and percent yield using the following: 2.0 g of salicylic acid and 5 mL of acetic anhydride, along with 10 drops of phosphoric acid, were used to make acetylsalicylic acid. This is a 1:1 mole ratio.
