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.

An efficient and inexpensive LiI-promoted O- to N-alkyl migration of 2-benzyloxy-, 2-allyloxy-, and 2-propargyloxypyridines and heterocycles is reported. The reaction produces the corresponding N-alkyl 2-pyridones and analogues under green, solvent-free conditions in good to excellent yields (30 examples, 20-97% yield).

Under irradiation of 456 nm blue light-emitting diodes, PPh3 catalyzes the iododecarboxylation of aliphatic carboxylic acid derived N-(acyloxy)phthalimide with lithium iodide as an iodine source. The reaction delivers primary, secondary, and bridgehead tertiary alkyl iodides in acetone solvent, and the

Stereoselective β-mannosylation is one of the most challenging problems in the synthesis of oligosaccharides. Herein, a highly selective synthesis of β-mannosides and β-rhamnosides from glycosyl hemi-acetals is reported, following a one-pot chlorination, iodination, glycosylation sequence employing cheap oxalyl chloride, phosphine
