Organometallic Ni(ii), Ni(iii), and Ni(iv) complexes relevant to carbon–carbon and carbon–oxygen bond formation reactions

Herein, the pyridinophane tetradentate ligand PyNMe3 is used to isolate and structurally characterize well-defined organometallic Ni(ii) and Ni(iii) complexes bearing the cycloneophyl fragment, an alkyl/aryl C-donor ligand.
