Enantioselective catalysis of organic transformations

untitled.gif
  The shape or architecture of a chiral catalyst has a profound effect on its ability to determine the stereochemistry of the organic reaction. As organometallic chemists we strive to design and synthesise catalysts in which the chirality is so well-expressed in the active site that the catalyst selectivity approaches perfection. While many groups around the world are working on this type of chemistry, our approach is quite distinctive in that we make catalysts in which are chiral-at-metal. We have developed new ways of generating beautiful chiral architectures.
Molecular materials such as chiral conductors and magnets

We have a particular interest in the synthesis of materials based on chiral building blocks and developing an understanding of how the physical properties of the material (conductivity, magnetism) are affected by their chirality.

Bioinorganic chemistry based on optically pure water-soluble complexes for healthcare applications

We have developed methods by which to assemble optically pure metal/ligand architectures that are stable in water and which interact selectively with DNA.

Discovery of new catalysts and processes for the industrial polymerisation of alkenes

Giles TBS

 

We are working on the applications of new early transition metal complexes in this area, and have particular interest in designing highly robust catalysts that may be applied in industrial situations. We are developing syntheses of copolymers of various kinds with industrial collaborators.
