Background
The prediction of the outcome of chemical reactions has long been a holy grail for synthetic chemists as it will allow the selection of the most efficient pathways to prepare high value commodity compounds. Preparing both new and known compounds in a timely and efficient manner is still a bottleneck for the chemical industry and considerable time and precious resources are routinely wasted on unsuccessful synthetic chemistry. This problem is made worse when the point of failure is close to the end of a multi-step synthetic route.
The routine prediction of chemical reaction outcomes will therefore greatly accelerate the delivery of, for example, new pharmaceuticals and agrochemicals. However, such prediction is challenging as reaction outcomes depend on the interplay between a large number of factors, from the fundamental properties of the reagents, through to the reaction conditions employed. This project is focussed on developing new methods to predict the outcome of reactions based on synthetic and mechanistic studies, closely coupled with computational chemistry.
Objectives
The principal objectives of this project are to develop a comprehensive model to predict the outcome of industrially important reactions. We wish to develop a tool that will all but guarantee the outcome of organic and inorganic reactions prior to laboratory work. The ultimate objective is to then use this insight to develop new, efficient, synthetic chemistry.
Experimental and Approach
The work will involve studying both organic and inorganic reactions through a range of different spectroscopic methods (e.g UV-vis, IR and NMR spectroscopy). Analysis of these experimental results will provide a rich dataset to build mechanistic models to understand the key factors controlling reaction outcomes. The model will then be developed by testing predicted reaction outcomes and then developed based on the accuracy of the results.
Novelty and Training The novelty of this programme lies in the coupling of mechanistic insight (i.e. rate constants, orders of reaction, identification of key intermediates) with computational chemistry to identify the factors which control the outcome of new chemical reactions. The student undertaking this project will be trained in state-of-the-art experimental mechanistic study to gain detailed understanding of the factors controlling reaction outcomes. There will also be an opportunity to develop additional skills, such as using computational chemistry to predict reaction outcomes, based on the experimental observations.
