Chapter 19, Problem 19.1(choose chapter or problem)
When benzene is treated with I2 in the presence of CuCl2, iodination of the ring is achieved with modest yields. It is believed that CuCl2 interacts with I2 to generate I +, which is an excellent electrophile. The aromatic ring then reacts with I + in an electrophilic aromatic substitution reaction. Draw a mechanism for the reaction between benzene and I +. Make sure that your mechanism has two steps, and make sure to draw all of the resonance structures of the sigma complex. I2 CuCl2
