Reactivity Profile of a Formally Dicobalt(0) Complex Bound by a Redox-Active Macrocycle.

ABSTRACT: In this article, we discuss the synthesis, characterization, and reactivity of a neutral dicobalt complex, [Co ₂ (PMe ₃ ) ₂ ] ⁰ , supported by a highly reduced, redox-active macrocyclic ligand. The reducing equivalents stored within the ligand framework proved capable of activating a wide scope of small molecule substrates. The addition of a weak acid, lutidinium triflate, led to the clean formation of a bridging hydride that was found to undergo fluxional geometric changes in solution, while exposure of [Co ₂ (PMe ₃ ) ₂ ] ⁰ to H₂ resulted in a rare example of net binuclear oxidativ
