A. Goal and Purpose:
Session 1: In this lab, we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First, there is a question of regioselectivity. Second, anthracene and its derivatives are highly visible under UV light.

Session 2: In this lab, we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR, the regiochemistry of the reaction.

E. Discussion and Conclusion

Session 1 (Partner up for this lab):
We assembled a drying tube. Into a clean dry 50 mL round-bottom flask, we added 2.0 g of anthracene and 15 mL of anhydrous chloroform. We made an ice-water bath in a beaker that will hold the 50 mL round-bottom flask and placed the ice-water bath on a stir plate in the hood. We had to do the following things as quickly as possible: weighing approximately 3 g of aluminum chloride and adding it to the 50 mL round-bottom flask, also placing a septum securely over the neck of the round-bottom flask and plunge the needle of the drying tube into the septum. We clamped the round-bottom flask in the ice-water bath that we put in the hood. We placed a disposable needle on a 10 mL plastic...
