资源简介：
A reactive
high-valent dinuclear nickel(IV) oxido bridged complex
is reported that can be formed at room temperature by reaction of
[(L)2Ni(II)2(μ-X)3]X (X = Cl
or Br) with NaOCl in methanol or acetonitrile (where L = 1,4,7-trimethyl-1,4,7-triazacyclononane).
The unusual Ni(IV) oxido species is stabilized within a dinuclear
tris-μ-oxido-bridged structure as [(L)2Ni(IV)2(μ-O)3]2+. Its structure and its
reactivity with organic substrates are demonstrated through a combination
of UV–vis absorption, resonance Raman, 1H NMR, EPR,
and X-ray absorption (near-edge) spectroscopy, ESI mass spectrometry,
and DFT methods. The identification of a Ni(IV)-O species opens opportunities
to control the reactivity of NaOCl for selective oxidations.
