Flash Communication: Structural Confirmation, Bonding, and Reactivity of an I(V) Analogue of Weiss’s Reagent

Structural confirmation of an iodine(V) analogue of Weiss’s reagent, [ArI-O(Pyr) 2 ] 2+, is reported using monodentate pyridine ligands and a nitro-substituted arene to provide protection from electrophilic aromatic substitution. The new complex is found to act as a source of electrophilic oxygen.
