Presentation Title

Ligand-based Reduction in Iron (II) Pyridinediimine Complexes with Brønsted Acid Secondary Coordination Sphere

Presentation Type

Poster

Abstract

Catalysis by metalloenzymes is often accompanied by the proximal access to protons near the active site. In synthetic systems, however, protonation near the metal center generally results in a prominent positive shift of redox potential, limiting electron transfer to the substrate. In order to understand the cause of this limitation, it is of our interest to investigate how the pKa and redox potential are coupled/uncoupled in synthetic ligand scaffolds. A family of Fe(II)PDI complexes with various pendant base in the secondary coordination sphere were synthesized and characterized.
