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.

temperature. A study of the effect that substituents on the aromatic ring have on the formation and stability of aryliodine(III) dichlorides shows that the transformation is easier to achieve in the presence of the electron-donating groups (i.e. methoxy), but in this case the products rapidly decompose under the reported reaction conditions to form chlorinated arenes. The results suggest that oxidation of
noncyclic hypervalent iodine nitrooxylating reagent is prepared from aryliodine diacetate and HNO3. This reagent facilitates the zinc-catalyzed regioselective nitrooxylation of cyclopropylsilylethers with broad scope, and also can be used in the nitrooxylation of various enolizable C−H bonds.
