Calculated mechanism of cis-dihydroxylation by BZDOp. All energies given are Gibbs free energy. The reaction was calculated on the S = 5/2 surface (red lines) and S = 3/2 surface (green lines). Schematics of the structures along the reaction coordinate are given and labeled at the bottom, with the DFT structures shown in Figure S5 and FMOs given in Figure S6. The electronic structure schemes for the Fe d orbitals, the substrate π orbital involved in the reaction, and the OH group are given at the bottom for the final four structures corresponding to the lowest energy spin state.
