Unformatted text preview: considered successful with a highly efficient purification process (though the same cannot be said for the reaction process). Overall, the products were collected in 12 test tubes and ran on three TLC plates. Based on the plates, some of the tubes with large amounts of Acetyl Ferrocene are also shown to contain trace amounts of ferrocene, which may have affected the melting point. Questions: 1. Write a detailed mechanism for the generation of the acylium ion (CH 3 CO) + from acetic anhydride and H 3 PO 4 . 2. What is the other product formed in the reaction of acetic anhydride with ferrocene? The reaction of acetic anhydride with ferrocene will produce not only acetyl ferrocene but also di-substituted 1,1-diacetylferrocene. It is darker in color and will not form as much as acetyl ferrocene because acyl is a deactivating group. 3. Show the structure of the intermediate formed in the reaction of ferrocene with the acylium ion....
