“Driving multi-electron chemistry using polynuclear reaction sites”
Presented by Theodore Betley, Harvard University

Abstract: Our efforts towards the preparation of polynuclear complexes as functional surrogates for polynuclear metallocofactors in biology will be discussed. We have developed a family of dendritic amide-based ligands to proximally orient multiple transition metal ions in a shared reaction space. The close M-M proximity can greatly influence the redox and reactivity patterns for these complexes, distinguishing the platforms from their monomeric components. Ligand modifications can directly control the M-M interactions to pursue different reactivities. The synthesis and characterization of these novel materials, as well as their reactivities as small-molecule activation platforms, will be described.
