A two-phase (CCl4/conc. hydrochloric acid) chlorination of some iodoarenes to the corresponding (dichloroiodo)arenes, prepared in 50-98% crude yields, is reported. Dichlorine is produced in the aqueous phase as follows:

KClO3 (solid) + 6 HCl (conc. aq.) → ↑3Cl2 + KCl + 2 H2O

biphasic chlorination - (dichloroiodo)arenes - iodoarenes - organic hypervalent iodine reagents
