In this lecture we will consider ways in which to maximise the potential of renewable feedstocks including biomass and carbon dioxide to generate key platform chemicals and high-value chemicals [1, 2]. We will show how certain catalytic processes can be significantly enhanced by carefully modifying the ionic liquid solvent. In this respect, using a mechanistic approach we have been able to dissect the influence of both the cation and anion of ionic liquids and show how each plays an important role in catalysed reactions. For example, the ions in an ionic liquid can interact directly with the catalyst, adjusting its electronic properties, or with the substrate, activating it via the formation of non-covalent interactions, or with the product, allowing kinetic products to be isolated. We also show that adjusting the strength of cation-anion interaction can significantly influence catalytic activity.

Since the valorisation of renewable feedstocks is likely to require multifactorial approaches, in the second part of the lecture we will consider how synthetic catalysis may be coupled to biocatalysis in order to fully utilize resources.
