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...

QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
