This project aims to prepare highly reactive rare earth organometallic and metal-organic compounds, especially from the free metals, and to determine their structures and reactivity. Abundant rare earth resources position Australia to be a major supplier of these strategic elements. The challenging target systems include coordination stabilised novel ligands, pseudo-Grignard reagents LnR(X) including the rare fluorides, complexes primed for carbon-fluorine activation, and intermediates from use of lanthanoid reagents in organic synthesis. The project will provide a knowledge base and expertise for the utilisation of Australia's abundant rare earths and will transform the current behaviour of the elements. It builds the expertise and knowledge needed to underpin Australian rare earth processing and develops the breakthrough science needed for new applications in fine chemical manufacturing, catalysis and recycling.Read moreRead less

Targeting Bio-Compatible Homo- and Hetero-bimetallic Cages and their Application in High Energy and Dual Energy Computed Tomography. The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved. Pre-requisites for cage design are that they be stable ....Targeting Bio-Compatible Homo- and Hetero-bimetallic Cages and their Application in High Energy and Dual Energy Computed Tomography. The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved. Pre-requisites for cage design are that they be stable and soluble in aqueous media, and be resistant to anionic ligand exchange at the cluster surface. The targeted metals are based on good attenuation at high (100 to 140 keV) and low X-ray (less than 30 keV) energies, and the possibility of high stability and low toxicity.Read moreRead less
New Look N-Heterocyclic Metallocenes of the Lanthanides Based on 4-Azapentalenyl Anions. Since there are abundant, but under utilised, reserves of lanthanide minerals in Australia, it is in Australia's best interest that their chemistry is developed into commercial applications in industrial catalysis. This project addresses this situation through the detailed study of carefully chosen organolanthanide compounds (specifically, comprising hetero-substituted metallocenes). The research strategy ....New Look N-Heterocyclic Metallocenes of the Lanthanides Based on 4-Azapentalenyl Anions. Since there are abundant, but under utilised, reserves of lanthanide minerals in Australia, it is in Australia's best interest that their chemistry is developed into commercial applications in industrial catalysis. This project addresses this situation through the detailed study of carefully chosen organolanthanide compounds (specifically, comprising hetero-substituted metallocenes). The research strategy will be directed towards advancing our knowledge in relation to fundamental chemical processes that are directly relevant to the industrial production of important commodity chemicals and polymers from often under utilised petroleum industry waste stocks.Read moreRead less
