Homogeneous Catalysis with Silver: Challenges and Opportunities
Presented by Prof. Michael G. Campbell
In recent years, synthetically useful homogeneous catalysis has been developed with silver; however, the mechanisms of silver-catalyzed redox reactions are generally still poorly understood. This talk will discuss our lab’s efforts towards better understanding the redox chemistry of well-defined silver complexes, with a focus on dinuclear complexes in which silver–silver interactions may play a role in facilitating multi-electron redox processes. First, we will present detailed experimental studies on the reactivity of a dinuclear silver(I) nitrene transfer catalyst, including the first examples of structurally characterized oxidation products obtained under catalytically relevant conditions. Second, we will discuss our efforts towards developing better ligand design principles for dimeric silver(I) complexes, in order to understand how modulating silver–silver interactions affects electronic structure and reactivity. Our results highlight both the promise and the challenges of developing new chemistry from this underappreciated metal.
