Mn(II), Fe(II), and Co(II) Aryloxides: Steric and Dispersion Effects and the Thermal Rearrangement of a Cobalt Aryloxide to a Co(II) Semiquinone Complex.

ABSTRACT: A series of Mn(II), Fe(II), and Co(II) bisaryloxide dimers ([M(OC₆H₂-2,4,6-Cy₃)₂]₂ {M = Mn (1), Fe (2), and Co (3)} were synthesized by the addition of 2,4,6-tricyclohexylphenol (HOC₆H₂-2,4,6-Cy₃) to the silyl amido dimers [M(N(SiMe₃)₂)₂]₂ (M = Mn, Fe, Co; Cy = cyclohexyl). An unexpected and unique Co(II) phenoxide derivative (4), [Co(OC₆H₂-2,4,6-Cy₃)(O₂C₆H-3,5,6-Cy₃)]₂, was obtained via ligand rearrangement of 3 at ca. 180 °C. This yielded 4 in which there are two unchanged, bridging phenoxide ligands as well as a terminal bidentate semiquino
