Richard J Whitby
- Primary position:
- Professor of Organic Chemistry
Richard Whitby graduated with a BA in Natural Sciences from Trinity College, Cambridge University in 1982. After a PhD with Professor P. G. Sammes at the University of Leeds and a fellowship with Professor P. J. Kocienski at the University of Southampton he was appointed to a lectureship at Southampton in 1988. In 1995 he was awarded the Society of the Chemical Industry 'Young Chemists' award, the Zeneca Research Award in Organic Chemistry and the Pfizer Research Award in Chemistry. In 1996, Richard Whitby became a Reader and was also awarded the GlaxoWelcome 'Innovative Chemistry' Research Award. He was promoted to Professor of Organic Chemistry in 1999, the year in which he received the Royal Society of Chemistry Bader award.
He has published chapters in two books on zirconium chemistry, contributed to special issues of Tetrahedron and Synthesis dedicated to Organotransition metal chemistry applied to organic synthesis and presented his work at many international conferences.
He originated and leads the ‘Dial-a-Molecule’ Grand Challenge (www.dial-a-molecule.org) which has the 20-40 year aim of making the synthesis of new molecules as quick and easy as it currently is to order a commercial compound.
His research interests include total synthesis, particularly using transition metal chemistry to rapidly assemble structures; Novel polyaromatic and heteroaromatic compounds for applications in molecular and organic electronics, photovoltaics, and Organic Light Emitting Diodes; The synthesis and properties of endohedral fullerenes (such as H2O@C60) using molecular surgery; The development of flow and automated chemistry, particularly using in-situ analysis to allow rapid optimization and mechanistic investigation; The synthesis and evaluation of biologically active molecules including agonists and antagonists of the orphan nuclear receptors LRH-1 and SF-1; Development of cheminformatics in synthesis, particularly developing ways of capturing, sharing and using detailed data on reaction execution and outcomes.
He is currently a member of the Organic Division Council of the Royal Society of Chemistry and on the advisory board of the national Chemical Database Service.

Prof. Whitby’s research interests span a wide range from using synthetic chemistry to tackle important scientific and societal problems, to developing the technology and informatics of synthesis itself. Current research interests include:
New synthetic methods using transition metals and application to organic synthesis. Our work focuses on various tandem processes using zirconocene templates to rapidly assemble complex organic structures. Particularly powerful has been methods based on the insertion of carbenoids into organozirconocene chlorides or zirconacycles. We have applied zirconium mediated key steps to the synthesis of several natural products. We have also developed a novel approach to chiral zirconocene complexes and applied them to catalytic carbomagnesiation and carboalumination reactions.
Ligands for Orphan Nuclear Receptors. We developed the first small molecule agonists for the important nuclear receptors SF-1 and LRH-1 with potential for application in a variety of biological and therapeutic areas including Stem Cell research and several cancers. Our molecules have been used in 20 laboratories worldwide to investigate the biology of these receptors. We are currently working on targets with better bioavailability, and aiming for antagonist activity.
Endohedral Fullerenes. We perform molecular surgery on fullerenes such as C60. The procedure involves opening a hole in the fullerene cage so that a small molecule such as H2 or H2O can be inserted, then suturing the opening to reform the pristine cage thus making endohedral fullerenes such as H2O@C60 and H2@C60. The molecules have fascinating quantum properties as a result of the presence or ortho- and para- spin isomers of the ‘H2’ systems. We recently ‘caged’ HF for the first time.
Flow chemistry. We are developing new synthetic methods which take advantage of flow chemistry (continuous processing) techniques. Currently we are working mostly on ‘reagentless’ methods such as using very high temperatures or photochemistry to achieve conversions. We also us flow techniques, particularly with the use of in-line IR, UV, and HPLC-MS, to allow rapid kinetic characterisation and optimisation of reactions.
Automated Chemistry and Closed Loop Optimisation. As part of a multi-disciplinary effort we are developing systems which will automatically and efficiently establish the scope and optimum conditions for reactions. The systems analyse the composition of reactions in real time and use the results to design and execute more experiments in an iterative process which should end with a complete reaction model. The work uses both flow and automated parallel batch reactors.
Organic electronics. We are designing and synthesising molecules with useful optoelectronic properties for application in organic electronics and photovoltaics. The work is lead by high level ab-inito calculations on properties. The current focus is on polyaromatic and heteroaromatic systems. Closely related is work on Molecular Electronics. We are designing and synthesising molecules which could form components of molecular circuits as well as working with colleagues from other disciplines on their electrical characterisation.
“Dial-a-Molecule” (http://www.dial-a-molecule.org) is an EPSRC funded Grand Challenge network which I lead. It is aimed at making the synthesis of novel molecules as quick as it currently is to order a stock chemical. A key to Dial-a-Molecule is to be able to predict the outcome of novel reactions, and hence the best way to do them and the best synthetic route. One requirement is high quality data on both successful and less successful reactions. We are working to facilitate the adoption of Electronic Laboratory Notebooks by academia as a way of ensuring that in the future such data is collected in a potentially usable form. We are also working on common data formats to enable sharing of such data and are looking forward to new ways to use the data.
