AI Article Synopsis
- - The one-electron oxidation of the palladium complex [Pd(IPr)] results in a stable mononuclear palladium(I) complex called [Pd(IPr)][PF], which has been fully characterized through various methods, including X-ray diffraction.
- - The unpaired electron is localized on the palladium metal center, as confirmed by EPR (Electron Paramagnetic Resonance) and DFT (Density Functional Theory) studies.
- - This palladium complex can reversibly bind and reduce dioxygen at low temperatures, producing a new three-coordinate complex, [Pd(IPr)(η-O)], where the unpaired electron is transferred to the superoxide ligand.
Article Abstract
The chemical and electrochemical one-electron oxidation of [Pd(IPr)] () leads to the formation of mononuclear palladium(I) complex [Pd(IPr)][PF] (). This bench-stable metalloradical has been fully characterized and its structure confirmed by X-ray diffraction analysis. EPR and DFT studies confirm the localization of the unpaired electron onto the metal center. Low temperature NMR and EPR measurements reveal the ability of complex to reversibly coordinate and reduce the dioxygen molecule, leading to the formation of a three-coordinate complex, [Pd(IPr)(η-O)] (), in which the unpaired electron has been transferred to the superoxido ligand.
