Switchable and stereocontrolled photoredox catalysis. This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in sit ....Switchable and stereocontrolled photoredox catalysis. This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in situ. This will enable the control of stereochemistry in photoredox reactions – not possible with standard catalysts - and establish other useful synthetic transformations. These strategies will make it easier to prepare valuable classes of organic molecules – efficiently, safely, and cost-effectively.

Nucleophilic carbenes as organocatalysts for asymmetric synthesis. Chemical compounds which come in two chiral mirror images (enantiomers) can have very different biological function. Often one form can have beneficial effects while the other can cause great harm (such as birth defects in the case of thalidomide). It is therefore very important for the drug industry to have asymmetric chemical reactions that lead specifically to only one enantiomer. The asymmetric reactions in this project ha ....Nucleophilic carbenes as organocatalysts for asymmetric synthesis.

Often one form can have beneficial effects while the other can cause great harm (such as birth defects in the case of thalidomide). It is therefore very important for the drug industry to have asymmetric chemical reactions that lead specifically to only one enantiomer. The asymmetric reactions in this project have been used previously to synthesise the anti-cancer metabolite roseophilin. The results of this project will ensure that there are many more similar success stories in the pharmaceutical and biotechnology industries.Read moreRead less
Metal complexes for activation and scission of small, multiply-bonded molecules. The outcome of this work is a series of metal complexes capable of cleaving the strong bonds in a number of small molecules of chemical importance. This will have a significant impact on industry by providing cheaper and safer alternatives to currently expensive and hazardous processes for producing nitrogen and phosphorus containing compounds.
