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.
