Observed reaction rates and second-order rate constants for 2 compared to other known non-heme Fe^IV=O models. Top (A): k_obs vs. the concentration of ethylbenzene in H-atom abstraction reactions. Bottom (B): k_obs vs. the concentration of thioanisole in oxo-transfer reactions. [Fe^IV=O(TBC)(CH₃CN)]²⁺ (2) (green), [Fe^IV=O(N₄Py)]²⁺ (orange), and [Fe^IV=O(TMC)(CH₃CN)]²⁺ (black).
