Abstract

MnO₄⁻ is activated by BF₃ to undergo intramolecular coupling of two oxo ligands to generate O₂. DFT calculations suggest that there should be a spin intercrossing between the singlet and triplet potential energy surfaces on going from the active intermediate [MnO₂(OBF₃)₂]⁻ to the O⋯O coupling transition state.
