The formation of oxygen-containing perfluorocyclohexadien-1-yliodine tetrafluorides

The electrophilic oxygenation of pentafluorophenyl iodo compounds C6F5IFn with iodine in different valencies (n = 0, 2, 4) using XeF2-H2O in HF allowed access to new organoiodine(V) compounds, namely isomeric oxopentafluorocyclohexadien-1-yliodine tetrafluorides, C6(O)F5IF4.
