Abstract

Nitrogen Dioxide-Catalyzed Electrophilic Iodination of Arenes. -Nitrogen dioxide is demonstrated to be an effective catalyst precursor for the iodination of alkoxy--substituted benzenes and naphthalenes. Mechanistic considerations show that the nitrosyl cation probably acts as virtual catalyst. Alkoxy-substituted substrates with blocked para-position as well as electron-deficient arenes exhibit only poor reactivity (not shown). -(REN, Y.-L.; SHANG, H.; WANG*, J.; TIAN, X.; ZHAO, S.; WANG, Q.; LI, F.; Adv.
