Reactions of Cp*3Co3(μ2-H)3(μ3-H) with Carbon Dioxide, Carbon Disulfide, and Phenyl Isocyanate

Journal Article (Journal Article)

The tetrahydride tricobalt cluster Cp* Co (μ -H) (μ -H) (1) reduces CO at 120 °C to form the dicobalt dicarbonyl complex [Cp*Co(μ-CO)] (2) in 45% yield by H NMR. 1 reacted with CS at room temperature to form the thiocarbonyl cluster Cp* Co (μ -CS)(μ -S) (3) in 19% isolated yield. 3 was characterized by X-ray crystallography and shown to consist of a triangle of cobalt atoms [Co-Co = 2.495 Å] capped on one face by a μ -sulfide ligand [Co-μ S = 2.129 Å] and on the opposite face by a μ -thiocarbonyl ligand [Co- μ -C ) = 1.949, μ -C-S = 1.634(5) Å]. 1 reacted with phenyl isocyanate at 55 °C to form the N,N′-diphenylureylene complex Cp* Co (μ ,μ -η -PhNCONPh) (5), the dicarbonyl tricobalt cluster Cp* Co (μ -CO) (6), and the carbonyl dimer 2. 5 was isolated in 13% yield and characterized by X-ray crystallography, which revealed that each nitrogen atom of the η -N,N′-diphenylureylene ligand was symmetrically bonded to both cobalt atoms [Co-Co = 2.456-(1), Co-μ -N = 1.959 Å]. © 1995, American Chemical Society.
