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
Quantum-chemical design of stereoregular polyphosphines for nanowires. In this project we will be designing and producing stereoregular polyphosphines that can self-assemble gold and silver complexes that mimic the molecular architectures of DNA and certain proteins. The longer gold complexes will behave as insulated nanowires, and are an exciting prospect for the development of nanotechnological devices. The shorter silver and gold complexes are expected to have significant antitumour propertie ....Quantum-chemical design of stereoregular polyphosphines for nanowires.

The longer gold complexes will behave as insulated nanowires, and are an exciting prospect for the development of nanotechnological devices. The shorter silver and gold complexes are expected to have significant antitumour properties. This project, which will use a unique theoretical-experimental approach to design the stereoregular polyphosphines, will enhance Australia's international scientific reputation, and will contribute to technological advancement in the national priority areas of nanotechnology and biotechnology.Read moreRead less
Towards Nano-circuits: 2 and 3-Dimensional Carbon-Wired Nano-architectures. Whilst Australia has a world-class profile in organotransition metal chemistry, main-group chemistry is under-represented, despite the enormous technological importance of materials based on these elements. In addition to the fundamental breakthrough science to be explored, the project will provide a training vehicle for 5 young scientists in both main group and organometallic chemistry. The target compounds involve an e ....Towards Nano-circuits: 2 and 3-Dimensional Carbon-Wired Nano-architectures. Whilst Australia has a world-class profile in organotransition metal chemistry, main-group chemistry is under-represented, despite the enormous technological importance of materials based on these elements. In addition to the fundamental breakthrough science to be explored, the project will provide a training vehicle for 5 young scientists in both main group and organometallic chemistry. The target compounds involve an essentially unique marriage of the fields of main-group and transition metal chemistry to provide complex nano-architectures based on the modular interconnection of metals and non-metals by carbon wires at the molecular level - nanoscopic counterparts of macroscopic circuit components.Read moreRead less
Understanding and Harnessing the Unique and Curious Metal Boron Bond: Unlocking the Metallaboratrane Cage. Metal-boron bonding holds enormous technological importance due to the emergence of boron-based metal-mediated synthetic transformations that access a diversity of high value-added fine chemicals.

Metal-boron bonding holds enormous technological importance due to the emergence of boron-based metal-mediated synthetic transformations that access a diversity of high value-added fine chemicals. Whilst Australia boasts an emergent boron-based fine chemicals industry, no research program into the nature of metal boron bonding exists to provide either fundamental science or advanced training in organometallic boron chemistry. The proposed work offers two distinct national benefits: The maintenance of a discipline in which Australia leads the world (metallaboratranes) and the genesis of one, which whilst intensely studied elsewhere, is notably absent from the Australian science base (low coordinate, unsaturated boron chemistry).Read moreRead less
Metal complexes for activation and scission of small, multiply-bonded molecules. The outcome of this work is a series of metal complexes capable of cleaving the strong bonds in a number of small molecules of chemical importance. This will have a significant impact on industry by providing cheaper and safer alternatives to currently expensive and hazardous processes for producing nitrogen and phosphorus containing compounds.
Boron and silicon based pincer ligands for environmentally responsible catalysis. The production of everyday chemicals (pharmaceuticals, agrochemicals, polymers) comes at a price, economic and environmental. Metal catalysts significantly reduce the environmental impact of both the associated energy requirements and waste products. New classes of catalysts will be developed based on the unconventional elements boron and silicon.
Earth Abundant Metal Complexes for Nitrogen Activation. This project aims to develop a range of complexes based around earth abundant metals that are capable of activating nitrogen (N2) at ambient pressure and temperature. 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 nitrogen.

This project aims to develop a range of complexes based around earth abundant metals that are capable of activating nitrogen (N2) at ambient pressure and temperature. 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 nitrogen. The activation of atmospheric nitrogen is performed on a multi-million tonne scale each year and is key to a number of industrial processes. As such, investigations into new and improved catalysts for this process would potentially bring huge financial benefits to industry, as well as benefiting the environment by reducing energy demand and associated climate change.Read moreRead less
Metallaboratranes: Soft Scorpionates and Masked Metal Bases. All molecular metal compounds involve a metal surrounded by a group of electron donors (?ligands?). The design and manipulation of these ligand sets and their interactions with metals (?coordination chemistry?) underpins ALL applications of metals, be they in biological, pharmaceutical, materials or industrial applications.

All molecular metal compounds involve a metal surrounded by a group of electron donors (?ligands?). The design and manipulation of these ligand sets and their interactions with metals (?coordination chemistry?) underpins ALL applications of metals, be they in biological, pharmaceutical, materials or industrial applications. This proposal addresses the diametric opposite - the role-reversal wherein a metal centre acts as an electron donor to a ligand. This rare situation has only recently been firmly established in this research group, but promises to be part of a wider new coordination chemistry, the limits of which will be pursued in the proposed work.Read moreRead less
