Valence-Inverted States of Nickel(II) Complexes Perform Facile C-H Bond Activation.
Wang S, Ma P, Shaik S, Chen H. Wang S, et al. J Am Chem Soc. 2022 Aug 17;144(32):14607-14613. doi: 10.1021/jacs.2c03835. Epub 2022 Aug 4. J Am Chem Soc. 2022. PMID: 35925767
For example, the so-generated (3)[(Ar)(bpy)Ni(II)(Br)] species possesses a valence-inverted occupancy, d(xy)(1)d(xz)(1)d(x(2)-y(2))(2), wherein the uppermost d(x(2)-y(2)) orbital is metal-ligand antibonding. This state promotes C-H bond activation of T …
