    Description / Table of Contents: Investigations to the Reactivity of Organonickel Compounds - “Spin Trapping” as an Indicator Method for the Relative Reactivity of Nickel-Carbon BondsThe spin trap nitrosodurene reacts with σ-alkyl, σ-aryl, π-allyl, σ-allyl, and π-cyclopentadienyl compounds of nickel(II) to form nitrosoduryl radicals which can be detected by ESR spectroscopy. Nickelolefine and nickel heteroolefine complexes do not react by formation of radicals. The spin trapping method can be generally used as an indicator for determination of structure elements in organonickel compounds and for determination of the relative reactivity of σ- and π-bonded groups.
    Notes: Das Spin-Trap-Reagenz Nitrosoduren reagiert mit σ-Alkyl, σ-Aryl, π-Allyl, σ-Allyl und π-Cyclopentadienylverbindungen des Nickel(II) unter Bildung von Nitrosodurylradikalen, die ESR-spektroskopisch nachweisbar sind. Nickel-Olefin- und -Heteroolefin-Komplexe reagieren normalerweise nicht unter Bildung von Radikalen. Die Spin-Trap-Methode kann allgemein als Indikatormethode zur Bestimmung von Strukturelementen an Nickelorganoverbindungen und zur Bestimmung der relativen Reaktivitäten von σ- und π-gebundenen Gruppen verwendet werden.
