  Synthesis oftris(Cyclohexylisocyanide)bis(Triphenylphosphine)Cobalt(II) Perchlorate. An Example of Unusual Stabilization of the Cobalt(II) Oxidation State.

  摘要：

  A cobalt(II) complex with alkylisocyanide and triarylphosphine ligands is reported. Tris(cyclohexylisocyanide)bis(triphenylphosphine)cobalt(II) perchlorate, [Co(CNC6H11)(3)(PPh3)(2)](ClO4)(2), was synthesized by PPh3 ligand-substitution in [Co(CNC6H11)(4)(AsPh3)(2)](ClO4)(2), in which the distribution of product among [Co(CNC6H11)(3)(PPh3)(2)](ClO4)(2), [Co(CNC6H11)(3)(PPh3)(2)]ClO4, [Co(OPPh3)(4)](ClO4)(2), and unreacted [Co(CNC6H11)(4)(AsPh3)(2)](ClO4)(2) was controlled in part by the concentration of PPh3 and reaction time. [Co(CNC6H11)(3)(PPh3)(2)](ClO4)(2) was also synthesized by AgClO4 oxidation of [Co(CNC6H11)(3)(PPh3)(2)]ClO4. [Co(CNC6H11)(3)(PPh3)(2)](ClO4)(2) is easily reduced to [Co(CNC6H11)(3)(PPh3)(2)]ClO4 with N2H4.H2O and decomposes into [Co(OPPh3)(4)](ClO4)(2) on prolonged dissolution in CH2Cl2 solution, especially under UV (365 nm) irradiation. Physical properties for [Co(CNC6H11)(3)(PPh3)(2)](ClO4)(2) and [Co(OPPh3)(4)](ClO4)(2) support trigonal bipyramidal and tetrahedral solution and solid state stereochemistries, respectively, but both complexes have limited stability in most solvents.
