General description
Iodine exhibits exceptionally high dielectric polarization in various solvents (dioxane, isobutylene, p-xylene and benzene).

Application
Catalyst for synthesis of esters by condensation of carboxylic acids with alcohols or transfesterification.

A mild and efficient method for esterification and transesterification catalyzed by iodine

Iodine has been used for the easy visualization of 9-bromononanoic acid, allyl ester by thin layer chromatography (TLC). It has also been used for the preparation of oxidation solution, required for the synthesis of oligodeoxynucleotides bearing 3′-terminal phosphorothioate.

Iodine may be used to catalyze:
Synthesis of 5-(4-nitrophenyl)-10,15,20-triphenylporphyrin.
Oxidative C-H bond amination of saturated hydrocarbons.
Protection of amines with benzyloxycarbonyl (Cbz) group.
Direct oxidative coupling/annulation of β-keto esters or 2-pyridinyl-β-esters with alkenes to form dihydrofurans and indolizine, respectively.
Thiocyanation of aromatic systems to form aryl thiocyanates.
Esterification of cellulose with acetic anhydride to form cellulose triacetate.
