Uses
ICl is a useful reagent in organic synthesis. It is used as a source of electrophilic iodine in the synthesis of certain aromatic iodides. It also cleaves C-Si bonds.
ICl will also add to the double bond in alkenes to give chloro-iodo alkanes.
- RCH=CHR’ + ICl → RCH(I)-CH(Cl)R’
When such reactions are conducted in the presence of sodium azide, the iodo-azide RCH(I)-CH(N3)R’ is obtained.
Wijs solution, which is iodine monochloride dissolved in acetic acid, is used to determine the iodine value of a substance.
