This is the second lecture from the course Chem 51C Organic Chemistry taught by David Van Vranken at UC Irvine in Fall 2020. I talk briefly about the dye Tyrian purple and it history in ancient Roman dress. I discuss the specific arrow-pushing mechanisms for generation of electrophiles in electrophilic aromatic substitution: Br-Br-FeBr3, nitronium ions, acylium ions, SO3H+, and carbocations. I talk about the effect of substituents on the rate and regiochemistry of subsequent electrophilic aromatic substitution or protons at the ortho, meta, and para positions.
