The synthesis of the divinylamido PNP nickel(II) complex [NiBr{N(CHCHPtBu2 )2 }] is reported. This compound exhibits reversible, ligand-centered oxidation and protonation reactions. The resulting pincer chemical non-innocence can be utilized for benzylic C-H hydrogen atom abstraction. The thermochemistry and kinetics of hydrogen atom transfer were examined.
