Nickel(II) and nickel(I) complexes with (S)-4-tert-butyl-2-(2-pyridyl)oxazoline (pyrox), [(pyrox)NiX2]n- (X = Br, 2,6-iPr2C6H3, Me3SiCH2, OAc; n = 0,1) were prepared and characterized by redox data, spectra and crystal structure determinations Low-valent organonickel radical complexes are common intermediates in cross-coupling reactions and metalloenzyme-mediated processes. The electronic structures of N-ligand supported nickel complexes appear to vary depending on the actor ligands and the coordination number The reduction products of a series of divalent (pyrox)Ni complexes establish the redox activity of pyrox in stabilizing electron-rich Ni(II)-alkyl and -aryl complexes by adopting a ligand-centered radical configuration. The reduced pyrox imparts an enhanced trans-influence. In contrast, such redox activity was not observed in a (pyrox)Ni(I)-bromide species. The excellent capability of pyrox in stabilizing electron-rich Ni species resonates with its proclivity in promoting the reductive activation of C(sp3) electrophiles in cross-coupling reactions.
