Ferrocene and Acylation of Ferrocene Discussion Pointers

REACTION DIAGRAMS AND MECHANISMS MUST BE INCLUDED IN THIS LAB REPORT! Make certain that you include the intermediate species that attacks ferrocene to form acetylferrocene. What other organic molecule is formed in the acylation of ferreocene reaction?

BRIEFLY discuss the type of mechanisms that both ferrocene and ayclation of ferrocene labs were based on in the INTRODUCTION SECTION of the lab report. Also in the introduction section offer consise background information on the ferrocene complex.

Discussion Section Pointers

When discussing your experimental results, be objective, and CONCISE! Discuss only relevant data, and provide adequate detail to justify your conclusions to the identity of your compound. The results should describe whether the goal or problem in the experiment has been resolved. Likewise, the experimental results are interpreted in this section and compared to literature results. If the reaction did not go as planned, and impurities or side reactions may have been the cause of complications in the reaction, include those in the discussion, and mechanism diagrams as well.

Include a yield discussion of both compounds synthesized. Include reasons for high or low yields. Include a BRIEF discussion on how you would imporve the procedure to minimize these errors.

If ferrocene is stable to air and all of the reagents are stable to air before the reaction begins, why must air be so carefully excluded from the reaction?

What is there about ferrocene that allows it to sublime easily where many other compounds do not?

Offer an a BRIEF explanation as to why the filtrate was blue / purple in color after suction filtering ferrocene product? Hint: Consult an Advanced Inorganic Chemistry Text (Cotton and Wilkenson) OR refer to the Comprehensive Inorganic Text, Volume 3, found in the Chemistry Library.

BRIEFLY offer an explanation as to why ferrocene and acetyl ferrocene are colored. (Hint: The answer can be found on this web page.)

Discuss the final TLC results of the pure ferrocene, the crude reaction mixture (acetylferrocene lab) and the recrystallized acetylferrocene.

In the formation of diacetylferrocene, the product is always the one in which each ring is monoacetylated. Offer a BRIEF explanation as to why the second acetyl group becomes linked to the unsubstituted ring and not the ring already containing one acetyl unit.

Likewise, during the Ferrocene acylation lab, why did we not have to use an aluminum chloride catalyst as it would normally be used in a Friedel-Crafts Acylation lab?
