Research interests

N-Heterocyclic carbenes (NHCs) are stable singlet carbenes that can act as excellent two electron donor ligands towards elements across the whole periodic table. They have received wide attention in transition metal chemistry and have a plethora of catalytic and biomedical applications. However, the use of NHCs in industry is still relatively limited due, in part, to their non-trivial synthetic procedures. We are developing novel synthetic routes to metal-NHCs which rely on electrochemistry rather than harsh basic conditions. Coupled with the translation into electrochemical flow reactors, we envisage metal-NHCs becoming more attractive for general use in important industrial processes.

The electrochemical synthesis of metal-NHCs enables more elaborate functional groups to be incorporated into the ligand structure, allowing for finer control at the metal centre. We are developing an electrochemical flow platform that incorporates high-throughput catalyst synthesis, screening and optimisation. Furthermore, we are interested in bringing together the two distinct and highly versatile ligand types, NHCs and carboranes, to take advantage of the unique properties of each moiety within one ligand structure.

We are involved in the development of metal-NHCs for both catalytic and biomedical applications. Our focus has been on copper- and iron-NHCs for catalysis, due to the lower cost and toxicity compared to precious metals, and the chemotherapeutic properties of silver-NHCs. We examine the reactivity of 'non-innocent' NHCs, as full mechanistic understanding of how these ligands behave will help in their design to prevent catalyst deactivation.
