Adding hydride punch to transition metal complexes for CO2 electroreduction. This project plans to apply an innovative methodology to the selective conversion of carbon dioxide (CO2) waste into useful C1 chemicals. The new inorganic chemistry approach is based on the invention of transition metal–organic hydride coordination complexes, which are designed to punch hydride ion (= a proton and two electrons) into metal-activated CO2-derived intermediates. The approach should naturally overcome the ....Adding hydride punch to transition metal complexes for CO2 electroreduction. This project plans to apply an innovative methodology to the selective conversion of carbon dioxide (CO2) waste into useful C1 chemicals. The new inorganic chemistry approach is based on the invention of transition metal–organic hydride coordination complexes, which are designed to punch hydride ion (= a proton and two electrons) into metal-activated CO2-derived intermediates. The approach should naturally overcome the two-electron barrier found for today's best transition metal electrocatalysts of CO2 reduction and, hence, enable the selective production of formaldehyde, a four-electron reduction product and bulk industrial feedstock chemical, or methanol, a six-electron reduction product and future transport fuel.Read moreRead less
A new era for modern main group chemistry: from landmark molecules towards the replacement of transition metal based technologies. This project will develop innovative approaches to access fascinating chemical compounds that were previously thought incapable of existence. These highly reactive, yet non-toxic systems will be exploited as cheap, environmentally benign replacements for the expensive and toxic metal based chemicals that are currently used in numerous technologies.

Summary
Heterometallic iron-molybdenum complexes for nitrogen activation. This project aims to develop a range of bio-inspired, mixed metal iron-molybdenum complexes that are capable of activating molecular nitrogen, N2, at ambient pressure and temperature. The activation of atmospheric N2 is performed on a multi-million tonne scale each year and is key to a number of industrial processes. The project expects to generate new knowledge in the area of organometallic chemistry, specifically with regards to ....Heterometallic iron-molybdenum complexes for nitrogen activation. This project aims to develop a range of bio-inspired, mixed metal iron-molybdenum complexes that are capable of activating molecular nitrogen, N2, at ambient pressure and temperature. The activation of atmospheric N2 is performed on a multi-million tonne scale each year and is key to a number of industrial processes. The project expects to generate new knowledge in the area of organometallic chemistry, specifically with regards to molecular metal-metal bonding and subsequent reactivity towards the activation of N2. Expected outcomes include new and improved catalysts, which will provide significant financial benefits to industry, as well as benefiting the environment by reducing energy demand.Read moreRead less
Understanding biological nitrogen fixation: an investigation of multi-electron reduction catalysis at novel iron-sulfur clusters. A new class of iron-sulfur clusters held together by a central light atom will be prepared and their reactions thoroughly studied. These clusters are important because they will have the same structure as the iron-molybdenum cluster of the enzyme nitrogenase. This enzyme fixes atmospheric nitrogen as ammonia. It is the primary route of nitrogen entry into all living s ....Understanding biological nitrogen fixation: an investigation of multi-electron reduction catalysis at novel iron-sulfur clusters. A new class of iron-sulfur clusters held together by a central light atom will be prepared and their reactions thoroughly studied. These clusters are important because they will have the same structure as the iron-molybdenum cluster of the enzyme nitrogenase. This enzyme fixes atmospheric nitrogen as ammonia. It is the primary route of nitrogen entry into all living systems. Industrially ammonia is produced in an energy-demanding process on a vast scale. The studies will provide insights into how nitrogenase works and how to design new multi-electron reduction catalysts. The research may lead to new energy-efficient routes to ammonia and to other new alternative fuel sources. Such processes would transform Australian industry and how we live.Read moreRead less
Asymmetric Synthesis of Chiral Phosphines, Arsines, and Stibines. There are now chiral phosphine-transition metal catalysts that rival enzymes in their efficiency for the asymmetric synthesis of important chiral drugs, fragrants, cosmetics, nutrients, vitamins, and pesticides. This project is aimed at a generalised asymmetric synthesis of the critical components of these enzyme mimics, notably enantiopure chiral phosphines, but also chiral arsines and stibines, by a highly innovative approach t ....Asymmetric Synthesis of Chiral Phosphines, Arsines, and Stibines. There are now chiral phosphine-transition metal catalysts that rival enzymes in their efficiency for the asymmetric synthesis of important chiral drugs, fragrants, cosmetics, nutrients, vitamins, and pesticides. This project is aimed at a generalised asymmetric synthesis of the critical components of these enzyme mimics, notably enantiopure chiral phosphines, but also chiral arsines and stibines, by a highly innovative approach that involves novel six-electron phosphenium, arsenium, and stibinium cations that are themselves stabilised by chiral phosphines so that chemical breeder reactions are possible. The use of chiral auxiliaries from the natural pool and from biotechnology will also be investigated.Read moreRead less
Development and Biological Chemistry of Novel Platinum Anti-Cancer Agents. "Rule-breakers", platinum anticancer complexes that do not follow the well established structure/activity relationships, have emerged as the way forward in the treatment of cancer resistant to the current generation of drugs and in reducing side effects. We have developed two new groups of "rule-breakers" and these have already demonstrated highly promising anticancer activity and novel biological behaviour.

"Rule-breakers", platinum anticancer complexes that do not follow the well established structure/activity relationships, have emerged as the way forward in the treatment of cancer resistant to the current generation of drugs and in reducing side effects. We have developed two new groups of "rule-breakers" and these have already demonstrated highly promising anticancer activity and novel biological behaviour. In this project we will (i) prepare new anticancer active platinum complexes based on these two highly promising groups of compounds and (ii) determine how these drugs work and what happens to them when in biological environments.Read moreRead less
