Application
2H,6H-[1,2]Iodoxolo[4,5,1-hi][1,2]benziodoxole-2,6-dione is an iodine(III) reagent that can be used:
- As a coupling reagent in many organic reactions like amidation, peptide coupling, and esterification to yield amides, esters, peptides, and macrocyclic lactones without racemization.
- As an oxidant in the arylation reactions of fluorophenols.
