Welcome to the homepage of Professor Andrew Weller, Department of Chemistry, University of York. 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 and B–H (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 and B–H. We make use of detailed kinetic and mechanistic studies to both understand and then improve the catalytic processes studied.
