title: Theoretical studies of iron(III)-catalyzed intramolecular C-H amination of azides.
abstract: Density functional theory calculations have been carried out to study the reaction mechanism of the [Fe(III)(F20TPP)Cl] catalyzed C-H amination reaction. The calculations show that the classical three-step mechanism for other metals (Ru, Rh, Ir and Zn), including N2 liberation, C-N bond formation and 1,2-hydrogen shift, does not fit the iron(III)-catalyzed system. After N2 liberation, the favorable reaction pathway for the iron(iii)-catalyzed system is a 1,2-hydrogen shift preceding C-N bond formation, i.e., a H-abstraction/radical rebound mechanism.
