Spin-State and Reorganization Energy Considerations for Metal-Centered Photoredox Catalysis.

ABSTRACT: Transition-metal complexes featuring metal-centered excited states have recently emerged as mechanistically distinct platforms for selective photochemistry, including photoredox catalysis. Among these, Co(III) complexes have demonstrated productive photoinduced electron transfer via the ³T₁ metal-centered state. In contrast, photoreactivity from the ⁵T₂ metal-centered state in Fe(II) polypyridyl complexes remains limited. Building on our prior report concerning reactivity associated with the ⁵T₂ state in [Fe(tren(py)₃)]²⁺ (tren(py)₃ = tris(2-pyridylmethyliminoethyl)-amine), we introduced stronger-field ligands in an effort to increase excited-state energies of Fe(II) polypyridyl complexes and
