Abstract: We report the isolation, characterization, and reactions of the unsaturated complex LᵗᴮᵘCo (Lᵗᴮᵘ = bulky β-diketiminate ligand). The unusual slipped kN,ɳ⁶-arene binding mode in LᵗᴮᵘCo interconverts rapidly and reversibly with the traditional k²N,N' ligation mode upon binding of Lewis bases, making it a "masked" two-coordinate complex. The mechanism of this isomerization is demonstrated using kinetic studies. LᵗᴮᵘCo is a stable yet reactive synthon for low-coordinate cobalt(I) complexes and is capable of cleaving the C-F bond in fluorobenzene.
