Title: Redox Non-Innocence of Nitrosobenzene at Nickel

Nitrosobenzene (PhNO) serves as a stable analogue of nitroxyl (HNO), a biologically relevant, redox-active nitric oxide derivative. Capture of nitrosobenzene at the electrondeficient β-diketiminato nickel(I) complex [iPr2NNF6]Ni results in reduction of the PhNO ligand to a (PhNO)./ ⁻ species coordinated to a square planar NiII center in [iPr2NNF6]Ni(η2- ONPh). Ligand centered reduction leads to the (PhNO)-2 moiety bound to NiII supported by XAS studies. Ultimately, systematic investigation of structure–reactivity patterns of (PhNO)./ ⁻ and (PhNO)2- ligands reveals parallels with superoxo (O2)./ ⁻ and peroxo (O2)2- ligands, respectively, and forecasts reactivity patterns of the more transient HNO ligand.
