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)?

These questions are from an experiment where we had a mixture of Ferrocene, acetylferrocene and diacetyl ferrocene and we separated each by using column chromatography. Before doing the column chromatography we did TLC analysis to ensure that we did, in fact, have a mixture of these 3 compounds. During the column chromatography we first eluted the ferrocene using pure hexane. Then we eluted the acetylferrocene using a 1:1 mixture of hexane and methylene chloride. Then we eluted the diacetylferrocene using...

question 4 & 5
Question 4 (2 points) if you accidently read the procedure wrong while doing the synthesis of aspirin and mixed Sg of salicylic acid with 2 mL of acetic anhydride (instead of correctly mixing 2g of salicylic acid with 5 mL of acetic anhydride), what would be the effect7(density of acetic anhydride = 1.082 g/mL) a Nothing, it would still work just fine Ob Reaction would work fine, but less product would form since acetic anhydride is...

Imagine a biochemistry lab is testing out a new procedure to improve the synthesis of a dipeptide molecule made with the amino acids Valine and Threonine. The hypothesis is that acid as a catalyst will improve the condensation reaction between the amino acids and create a greater yield of a dipeptide (molecule formed with these two amino acids). The procedure compares the result of 10 samples using the common older procedure (A) to ten samples using the newer acid synthesis...
