Unprecedented Rate Enhancements of Hydrogen‐Atom Transfer to a Manganese(V)–Oxo Corrolazine Complex

Abstract

Runaway reactivity: A manganese(V)–oxo porphyrinoid complex displays an unprecedented increase in reaction rate for a hydrogen-atom abstraction upon addition of anionic axial ligands (X=F− and CN−; see scheme). Density functional theory calculations are in excellent agreement with experiment, and provide insight into the origins of these remarkable axial ligand effects.
