<h2 class="heading hide-accessible">Summary</h2>

Ligand design is essential in the development of coordination and organometallic complexes, allowing their overall properties to be tuned and controlled in a precise manner, enabling new activities and reactivities to emerge. N-Heterocyclic carbenes (NHCs) have been studied widely as ancillary ligands for the preparation of metal-based catalysts, and have shown significant promise. The steric and electronic versatility of NHCs is huge, through alteration of the nitrogen substituents and carbon backbone substituents. We have shown that electrochemical methodology can be used for the synthesis of metal-NHCs and other metal complexes.<br /> <br /> Our route surpasses traditional synthetic routes as it negates the need for strong bases, strict inert conditions, the by-product formation of stoichiometric metal salts, and is compatible with a wide range of ligand functionalities. We have translated the methodology into flow technology, enabling efficient and facile &amp;lsquo;on-tap&amp;rsquo; generation of a range of organometallic, inorganic and coordination compounds.<br /> <br /> This project will involve electrochemical generation of base-metal catalysts with direct flow into a catalytic flow reactor. Inline analysis at both the complex synthesis and catalytic reaction stages will enable optimisation of the full process using feedback control systems. Students working on this project will gain skills in synthetic organic and organometallic chemistry, catalysis, flow-chemistry and reaction engineering. In addition, a variety of analytical tools will be used including NMR and UV spectroscopy, (in-situ) mass spectrometry, GC and X-ray crystallography.<br /> <br /> The industrial standard lab that is housed in the School of Chemistry at Leeds (iPRD) and the interdisciplinary research project will provide a unique and relevant training environment.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="https://www.leeds.ac.uk/info/130206/applying/91/applying_for_research_degrees">University&#39;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is &lsquo;Electrochemical synthesis, catalyst screening and optimisation of base-metal catalysts using a flow reactor platform&rsquo; as well as <a href="https://physicalsciences.leeds.ac.uk/staff/201/dr-charlotte-willans">Dr Charlotte Willans</a>&nbsp;as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
