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

adduct (UHP), a stable, inexpensive, and easily handled oxidant. The reactions were complete in 15 min at 85 °C. The melts thus obtained were reacted with excess hydrochloric acid to afford crude (dichloroiodo)arenes, ArICl2, in 64–98% yields.

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.

simple method for the functionalization of closo‐borates [closo‐B10H10]2− (1), [closo‐1‐CB9H10]− (2), [closo‐B12H12]2− (3), [closo‐1‐CB11H12]− (4), and [3,3′‐Co(1,2‐C2B9H11)2]− (5) is described. Treatment of the anions and their derivatives with ArI(OAc)2 gave aryliodonium zwitterions, which were sufficiently stable for chromatographic purification. The reactions of these zwitterions with nucleophiles

Arenes (ArH) were substituted with some transient I3+ species, generated in situ in appropriate, anhydrous I2/NaIO4 or NaIO3/AcOH/Ac2O/concd H2SO4 mixtures, to form soluble organoiodine(III) intermediates, ArISO4. Next, excess concd hydrochloric acid was added to precipitate out the title ArICl2, and isolated in 46–88% optimized crude yields.
