Abstract
The oxidative addition reaction of methyl iodide to rhodium or iridium complexes were investigated, incorporating various orthro-substituted dimethylphenylphosphine ligands on the metal complexes. Evidence of rate enhancement for the oxidative addition reaction of the various complexes with methyl iodide was found, due to the influence of the ortho-substitutes. The complexes studieded were:Carbonyl (chloro) bis-[o-chlorophenyl (dimethyl) phosphine] -rhodium (I)Carbonyl (chloro) bis-[o-bromophenyl (dimethyl) phosphine] -rhodium (I)Carbonyl (chloro) bis-[dimethyphenlphosphine] -rhodium (I)Carbonyl (chloro) bis-[o-chlorophenyl (dimethyl) phosphine] -rhodium (I)The increase in relative reaction rates for the complexes were found to proceed in the order: Br \u3e Cl \u3e H for ortho-phenyl substituent and Ir (I) . Rh (I) for complexes of similar ligand type
