the preparation of iodoarene dichlorides from iodoarenes have been developed. One employs solid sodium chlorite as a chlorinating agent in dilute hydrochloric acid solution; the other uses sodium hypochlorite as a chlorinating agent still in hydrochloric acid solution, which is more robust than the sodium chlorite system. Typically, the preparation of iodobenzene dichloride from iodobenzene was performed

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.

α-ketoacid could be converted into a reactive acylating agent by treatment with hypervalentiodine(III) species, and in so doing, we discovered a novel decarboxylative acylation of alcohols that affords a variety of esters in excellent yields. The esterification has been applied to a sterol bearing a free carboxylicacid and shows unique chemoselectivity. The procedure is racemization-free and operates

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.
