Dr Andrew Johnson

Profile

Research activities and interests within the group focus on several different aspects of the synthesis, structure bonding and reactivity (both fundamental and catalytic) of new organometallic and coordination compounds, with much of the chemistry we study falling under the banner of metal alkoxide chemistry, but not exclusively.

Our work involves a major synthetic component, most of which is carried out using inert atmosphere techniques. And relies heavily on multinuclear NMR, and X-ray cryatallography as a unifying theme to all the chemistry studied is an interest in structure reactivity relationships.

Research Interests

  • Metal-Alkoxide Coordination Chemistry
  • Lewis acid Reagents
  • New Catalysts for the Polymerisation of Cyclic Esters

All of these projects are evolving and updated on a regular basis, anyone interested in aspects of our work please contact us at the addresses given above.
