Conceptual Checkpoint 18.01 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 . For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer. Do not draw out any hydrogen explicitly in your products. Do not use abbreviations such as Me or Ph.
