Iodination









Common Conditions:


SEAr (Electrophilic Aromatic Substitution)

Iodine is the least reactive halogen in aromatic substitutions, but sufficiently activated aromatic substrates (ex. anilines or phenols) readily react. The most common reagents are iodine and N-iodosuccinimide (NIS).





Lithiation / Iodination

Lithiation followed by electrophilic quench with iodine is a common method for iodination. Lithiation of substrates is typically carried out by organolithiums (ex. n-BuLi, s-BuLi, or t-BuLi) or a hindered lithium amide base (ex. LDA).
