Application

Lithium iodide (LiI) can be used as a catalyst to synthesize:
  • N-alkyl 2-pyridone derivatives via O- to N-[1,3]-alkyl migration.
  • β-mannosides and β-rhamnosides from glycosyl hemiacetals via one-pot chlorination, iodination, and glycosylation reaction.

It can also be used as:
  • Solid electrolyte in the synthesis of Vycor glass/LiI composites applicable in the development of solid-state batteries.
  • Iodine source to synthesize primary, secondary, and bridgehead tertiary alkyl iodides by PPh3-catalyzed iododecarboxylation of aliphatic carboxylates.
