Aryl Halides | CAMEO Chemicals | NOAA

Aryl halides do not participate in conventional SN2 nucleophilic aromatic substitution reactions. Instead the halides are displaced by strong nucleophiles via reactions involving radical anions. On the other hand, aryl halides, especially the bromides and iodides, undergo oxidative addition with transition metals, and thus are subject to ...
