文摘

The nickel(II) complex [Ni(Tp^Me2) (SC₆H₄NO₂)] [1a; Tp^Me2 = hydrotris(3,5-dimethylpyrazol-1-yl)borate] reacts with O₂ to form the ligand oxygenation product ArSO₂^{鈥?/sup> in MeCN, and also 1a catalyzes the oxygenation of external substrates such as triphenylphosphine. The reactivity may correlate to the unique quinoid-like resonance structure of the thiophenolate ligand. The structure is stabilized by a p-nitro group and induced by coordination of MeCN.}
