I will introduce this paper at next journal meeting.
This paper report the smooth reductive O2 binding in the cleft of a dinickel(II) core via elimination of H2 from the corresponding dinickel(II) dihydride complex.
This was the first μ-1,2-peroxo dinickel intermediates to be characterized by X-ray diffraction.
This work provides an entire new series of closely related and comprehensively characterized (including elemental analyses) Ni2/O2 intermediates, viz. the mutually interconvertible μ-1,2-superoxo and μ-1,2-peroxo species as well as the K+ adduct of the latter, all based on the same pyrazolate-based {LNi2} scaffold.
