The reactions of cyclopentadienyl(dimethylphenylphosphine)carbonylrhodium with halogens and organic halides
Oliver,Graham
, p. 243 - 247 (1970)
At low temperatures C5Hr5Rh(CO)L, 1 (L = P(CH3)2C6H5), reacts with Cl2, Br2, CH3COBr, and CF3COCl forming isolable [C5H5Rh(CO)LX] +X- or [C5H5Rh(CO)L(COR)] +X- which were converted to their more stable tetraphenylboron salts. At room temperature the ionic dihalides lose CO forming neutral C5H5RhLX2. Alkyl halides (CH3Cl, CH3Br, CH3I, C3H5Cl) react with 1 forming acyl derivatives C5H5RhL(COR)X in a reaction thought to proceed via ionic [C5H5Rh(CO)LR] +X-.

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.
Kinetics and mechanism of oxidative addition reactions. I. Reactions of methyl iodide and ethyl iodide with π-cyclopentadienylcarbonylphosphine complexes of cobalt, rhodium, and iridium
Hart-Davis,Graham
, p. 2658 - 2663 (2008/10/08)
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.
