Acetylation Of Ferrocene Essay Research Paper 17 Example.
Acetylation of Ferrocene. Introduction. In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process.
Carbon Acetylation of ferrocene Due to the aromatic character of the cyclopentadienyl ligands, ferrocene can undergo electrophilic aromatic substitution reactions typical of aromatic compounds such as benzene. In this experiment you will acetylate ferrocene via the Friedel-Crafts acylation reaction. Safety Phosphoric acid (H3PO4) and acetic anhydride ((CH3CO)2O) are irritants. Avoid breathing.
The use of ferrocene-based compounds for medicinal applications is an active research area. Many reports have demonstrated that some ferrocenyl derivatives are highly active against several diseases, including cancer. This review focuses on the most relevant examples of ferrocene-based molecules that show an In honour of Didier Astruc.

Experiment 14: The Friedel-Crafts Acylation of Ferrocene A Friedel-Crafts acylation is an electrophilic aromatic substitution reaction that introduces an acyl group onto an aromatic ring. The electrophile is an acyl cation that is often coupled to a Lewis acid catalyst, such as aluminum chloride. In order for the reaction to take place, the aromatic ring system must be very electron rich and.
Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2. The molecule consists of two cyclopentadienyl rings bound on opposite sides of a central iron atom. It is an orange solid with a camphor-like odor, that sublimes above room temperature, and is soluble in most organic solvents. It is remarkable for its stability: it is unaffected by air, water, strong bases, and can be.
Add 200 mg of ferrocene, 1.0 mL of acetic anhydride, and 0.3 mL of phosphoric acid to a large reaction tube and stir. Heat the tube to a gentle reflux using a water bath with constant stirring for 10 minutes. Note the color during the reaction. Cool the reaction tube to room temperature. Add dropwise 1.5 mL of ice water, followed by 3M NaOH solution until the resulting product mixture tests.
