Redox chemistry and H-atom abstraction reactivity of a terminal zirconium(iv) oxo compound mediated by an appended cobalt(i) center.

ABSTRACT: The reactivity of the terminal zirconium(iv) oxo complex, O[triple bond, length as m-dash]Zr(MesNPⁱPr₂)₃CoCN ^t Bu (2), is explored, revealing unique redox activity imparted by the pendent redox active cobalt(i) center. Oxo complex 2 can be chemically reduced using Na/Hg or Ph₃C^• to afford the Zr^IV/Co⁰ complexes [(μ-Na)OZr(MesNPⁱPr₂)₃CoCN ^t Bu]₂ (3) and Ph₃COZr(MesNPⁱPr₂)₃CoCN ^t Bu (4), respectively. Based on the cyclic voltammogram of 2, Ph₃˙ should not be sufficiently reducing to achieve the chemical reduction of 2, but s
