Abstract

Oxidation of NH₃ to N₂ by pentapyridyl metal complexes via hydrogen atom abstraction was investigated computationally. Quantum chemical analysis reveals insights on orbital symmetry requirements for efficient NH₃ oxidation. The most promising complex, [(PY5)Mo(NH₃)]²⁺, was studied experimentally. It shows conversion of NH₃ to N₂ upon treatment with 2,4,6-tri-tert-butylphenoxyl radical.
