| 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  |
| Application: | 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. |
| Application: | Iodine may be used to catalyze: • Synthesis of 5-(4-nitrophenyl)-10,15,2 • 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. |
| General description: | Iodine exhibits exceptionally high dielectric polarization in various solvents (dioxane, isobutylene, p-xylene and benzene). |
