A kinetic study of the oxidative addition of methyl iodide to [Rh((C4H3S)COCHCOCF3)(CO)(PPh3)] utilizing UV/vis and IR spectrophotometry and 1H, 19F and 31P NMR spectroscopy. Synthesis of [Rh((C4H3S)COCHCOCF3)(CO)(PPh3)(CH3)(I)]

The oxidative addition kinetics of CH3I to [Rh((C4H3S)COCHCOCF3)(CO)(PPh3)], studied by UV/vis, IR and NMR techniques, consists of two reaction steps involving two isomers each of a RhIII-acyl and two different RhIII-alkyl species.
