Research Priorities: Organocatalysis, catalysis concepts, proline-catalysed intermolecular aldol-reaction, asymmetrical catalysis, textile-organic catalysis
Benjamin List is a chemist. He co-founded the field of asymmetrical organocatalysis – a process with which molecules can be constructed. Organocatalysts are used, for example, in the production of drugs and solar cells. Their advantage is that they do not require metal compounds, which are often detrimental to health or the environment and comparatively expensive. For the discovery of this third class of catalysts, he was awarded the 2021 Nobel prize in chemistry together with David W.C. MacMilan.
Benjamin List found that the naturally occurring amino acid proline is an efficient catalyst (proline-catalysed intermolecular aldol-reaction) and thus opened the field of organocatalysis. With that, naturally occurring substances and nonmetals could be used as catalysts for the first time in chemistry. Previously, only two types of catalysts – which accelerate chemical reactions and make them more efficient – were known: metal catalysts and enzymes. By comparison, organic catalysts are more easily reusable and generally less toxic than metal catalysts. They contribute to a chemistry that is more sustainable and more resource efficient as 80 per cent of all chemical products are made with the help of catalysts.
Together with his team, Benjamin List discovered new principles of asymmetric catalysis (asymmetric counteration-directed catalysis, ACDC) and textile-organic catalysis. During textile-organic catalysis, soluble organic catalysts are sequestered to textile materials. This principle can help to treat water where people are cut off from water supply.
