A terminal carbonyl of CpCo(CO)2 inserts into the U=C bond of Cp3U=CHPMeRPh (R = Ph or Me) to produce Cp(OC)CoC(OUCp3)=CHPMeRPh. The structure of Cp(OC)CoC(OUCp3)=CHPMe2Ph has been confirmed by X-ray diffraction: space group P212121; a = 15.645 (2) ?, b = 23.828 (3) ?, c = 15.140 (3) ?, α = β= γ = 90°; final error indexes R = 0.0555, RG = 0.0644 for 3433 unique data with I > 3σ(I). Heating Cp(OC)CoC(OUCp3)=CHPMeRPh leads to the formation of Cp(OC)CoPMeRPh.

A kinetic study of the oxidative addition reaction of π-C5H5M(CO)L (where M = Co, Rh, Ir and L = tertiary phosphine) with CH3I and C2H5I has been carried out. The reactions are first order in both metal complex and alkyl iodide. Rates are slightly greater for M = Ir than for M = Co or Rh, are much greater for CH3I than for C2H5I, and increase with increasing solvent polarity. The reactions are discussed in terms of the nucleophilicity of the metal atom.
