Aiming at the enhancement of electrophilicity of imino-λ3-iodanes, we have developed (tosylimino)pentafluorophenyl-λ3-iodane, which shows superior reactivity compared to the commonly used (tosylimino)phenyl-λ3-iodane in the [2+2+1]-type synthesis of imidazoles. (Figure presented.).

Ceric ammonium nitrate (CAN) has been found to be a remarkable oxidizing agent for the oxidative conversion of iodoarenes to (dichloroiodo)arenes in acetic acid using aqueous HCl. The reaction of CAN with HCl generates in situ molecular chlorine, which is responsible for the oxidation. This method avoids the use of hazardous, toxic, and corrosive gaseous chlorine.

One improved and eight novel oxidative, liquid-phase chlorination procedures for the preparation of (dichloroiodo)arenes, ArICl2, from iodoarenes, ArI, are presented. KMnO4, activated MnO2, KCIO3, NaIO4/su
Liquid-phase and biphasic chlorination of some iodoarenes to form (dichloroiodo)arenes with sodium peroxodisulfate as the oxidant

, p. 435 - 437 (2007/10/03)
Liquid-phase and biphasic (CCl4/concd hydrochloric acid) chlorination of some iodoarenes to form the corresponding (dichloroiodo)arenes, prepared in 60-100% crude yields, are reported; dichlorine is produced as follows: Na2S2OP8 + 2 HCl (conc. aq.) → Cl2 + 2 NaHSO4.
Oxidative chlorination of various lodoarenes to (dichloroiodo)arenes with chromium(vi) oxide as the oxidant j

, p. 64 - 65 (2007/10/03)
Chromium(vi) oxide dissolved in a mixture of acetic acid with concentrated hydrochloric acid converts, at or near room temperature, iodoarenes to (dichloroiodo)arenes, in a very simple and efficient procedure.
Biphasic chlorination of iodoarenes to (dichloroiodo)arenes

, p. 1409 - 1410 (2007/10/03)
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 + 3H2O.
