Single or Double? A Radical Approach to Main Group Catalysis

Can the use of d-block elements be circumvented in catalysis?The knowledge base of chemical transformations involving transition metal species is vast. Indeed, the versatility of transition metals has rendered them indispensable for a substantial number of transformations. Yet, the corresponding reactivity of compounds derived from the p-block elements is much less studied. However, in the last two decades, a number of advancements has inspired a renaissance in the chemistry of the p-block particularly in the realm of catalytic transformations. With commercial interest in main group catalysts stemming from reduced purification costs, potential lower toxicity, different functional group tolerances or alternative selectivity, there has been a drive to develop new p-block systems for synthesis and catalysis. In this project I aim to deepen the understanding of radical frustrated Lewis pairs, and to develop catalytic protocols for the synthesis of useful compounds. Alongside this I will develop flow and flow electrochemistry as enabling tools in main group chemistry to address current challenges in catalysis and sustainable chemistry. Overall, this work will cover both fundamental and applications-driven research, demonstrating a diversity of chemical transformations of the p-block elements as well as the use of enabling technologies including flow chemistry, electrochemistry, and electron paramagnetic resonance (EPR) spectroscopy. Collectively, the work packages (WPs) described herein will illustrate new strategies in synthesis and novel reactivity that will lead to a deeper understanding and applicability of these elements. Indeed, the discovery of new synthetic methodologies is crucial for developing novel compounds leading to new pharmaceutical leads, resulting in economic and societal benefits. The work outlined in this ERC proposal will further the resurgence of p-block chemistry providing fresh insights into both organic and main group chemistry.
