The reactions of cyclopentadienyl(dimethylphenylphosphine)carbonylrhodium with halogens and organic halides

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-.

Kinetics and mechanism of oxidative addition reactions. I. Reactions of methyl iodide and ethyl iodide with π-cyclopentadienylcarbonylphosphine complexes of cobalt, rhodium, and iridium

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.
