Question

What is the mechanism (with curved arrows) for this reaction?

1. Add about 1.0 g (measured accurately) of acetophenone to 40 mL of the bleach solution (5% NaCl in water - this reactant should be included in your table of reagents!) in a 100 mL round bottom flask equipped with a magnetic stirrer. Clamp the flask in the fume hood above a stir plate. 2. After the initial reaction has subsided, boil the reaction mixture gently for 5 - 10 minutes using a heating mantle. 3. Monitor the reaction by using TLC. 4. Add 0.5 mL of acetone to destroy any unreacted hypochlorite (how?) and boil gently for another 15 minutes to remove the chloroform and unreacted acetone. 5. If your solution is very dark, add a small amount of decolorizing charcoal and filter the solution while it is still hot. 6. Pour the mixture into a 125 mL Erlenmeyer flask using a filter funnel and place the flask in an ice bath. Acidify the solution by adding concentrated HCl drop-wise until the pH is near 1 and no more precipitate forms. Keep the mixture in the ice bath for an additional 5 minutes to complete the precipitation. 7. Filter the product by suction filtration using a Buchner funnel (with an initial gravity filtration as performed in previous experiments). Wash the crystals with about 5-10 mL of cold water and let them dry. 8. Determine the melting point and the yield of your product once the crystals have dried at the end of the lab period.
