Research in the Weller group is based upon synthetic organometallic chemistry and catalysis, and in particular the generation and stabilisation of transition metal complexes with a low coordination number. These complexes often show very interesting, and novel, structures that display C–H, B–H and C–C bonding modes (via agostic or sigma interactions). Not only are we interested in the fundamentals of synthesis, bonding and structure of these complexes, but we also have a focus on their use and development in challenging catalytic bond transformations, such as C–H, B–H and C–C activation. Collaborations with synthetic organic chemists (Professor Michael Willis, Oxford), computational chemists (Professor Stuart Macgregor, St Andrews, experts in the study of mechanism using kinetics (Professor Guy Lloyd–Jones, Edinburgh) and novel analytical techniques (Professor J. S. McIndoe, University of Victoria), and Inorganic Materials Chemists also lead to a deeper understanding of structures and reactivity and applications of many of the new complexes and catalytic systems discovered
