A similar iridium complex was studied. It was found that the reaction with a Tp ligand where R = Me
occurred with a very high rate (tsp< 5 s at0 °C), while the unsubstituted Tp complex had a much slower
ligand substitution rate (tap = 75 min at room temp). Based on this result, does this complex undergo
ligand substitution by the same mechanism as the ruthenium complex, or by another mechanism.
Explain.
