Abstract

Previous experimental results revealed that the C-H bond activation reaction by a synthetic trans-dioxo Mn^V porphyrin complex, [(TF₄TMAP)OMn^VO]³⁺, does not occur via the well-known oxygen rebound mechanism, which has been well demonstrated in Fe^IVO porphyrin π-cation radical reactions. In the present study, theoretical calculations offer an explanation through the energetics involved in the C-H bond activation reaction, where a multi-spin state scenario cannot be excluded.
