DESCRIPTION
General description
Iodine exhibits exceptionally high dielectric polarization in various solvents (dioxane, isobutylene, p-xylene and benzene).[1]
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).[2] It has also been used for the preparation of oxidation solution, required for the synthesis of oligodeoxynucleotides bearing 3′-terminal phosphorothioate.[3]
Iodine may be used to catalyze:
- Synthesis of 5-(4-nitrophenyl)-10,15,20-triphenylporphyrin.[4]
- Oxidative C-H bond amination of saturated hydrocarbons.[5]
- Protection of amines with benzyloxycarbonyl (Cbz) group.[6]
-  Direct oxidative coupling/annulation of β-keto esters or 2-pyridinyl-β-esters with alkenes to form dihydrofurans and indolizine, respectively.[7]
- Thiocyanation of aromatic systems to form aryl thiocyanates.[8]
- Esterification of cellulose with acetic anhydride to form cellulose triacetate.[9]
