Light-driven Fe-catalysed reduction of C-C multiple bondsAn approximation to the direct use of alkenes and alkynes as nucleophilic alkyl-/alkenyl- synthons

  • Supervisor: Dr Xacobe Cambeiro
  • Deadline: 10th January 2018
  • Funding: China Scholarship Council

Expressions of interest are invited for a CSC-funded PhD studentship to work on homogeneous catalysis under the supervision of Dr Xacobe Cambeiro at Queen Mary University of London (QMUL). 

Project

The main objective of this research project is to develop new and sustainable methods for the reduction of alkenes and alkynes combining bioinspired Fe-based catalysts, photocatalysts and visible light as a source of energy. 
Catalytic hydrogenation and related hydrofunctionalisation of alkenes and alkynes are among the most relevant transformations in chemical industry in terms of scale, and they are vital for a number of industries. However, these methods find important challenges in terms of sustainability, namely: (i) They make extensive use of precious metal catalysts, such as Pt, Rh or Ir, and (ii) To be thermodynamically favoured, they require the use of strong reductants such as H2 or reduced metals. Methods for catalytic hydrogenation using Earth-abundant metals such as Fe aim at addressing challenge (i). In our group, with the use of photocatalysis, we aim to capture the energy of light to promote such reactions with mild, clean reductants such as amines or ideally¬¬ water, which would be otherwise unreactive. 

The successful applicant will work towards this objective by studying the reactivity or organometallic Fe complexes –including Fe hydrides and alkyl-Fe compounds– against organic substrates, as well as developing new methods for the light-driven generation of these important Fe intermediates. The project will require the evidence-based design of complex multimetallic catalytic cycles, using a wide range of methods and instruments for mechanistic investigation. 

Techniques and Training

The student will receive training in organic synthesis and organometallic chemistry, including advanced experimental and computational techniques for the investigation of reaction mechanisms. Laboratory techniques will include standard organic and organometallic synthesis, Schlenk techniques for working under inert atmosphere, as well as photochemistry. In addition, the applicant will have the opportunity to acquire relevant transferable skills, such as oral and written presentation of research results and supervision of less experienced researchers. QMUL has free language courses available for students not having English as their mother tongue. 

Research Environment

The successful PhD student will join a vibrant group of young researchers in the homogeneous catalysis laboratory at QMUL, a modern and well-equipped laboratory hosting several groups of research on organic, inorganic and organometallic chemistry. This varied group will provide excellent opportunities for learning and discovering new areas of research in homogeneous catalysis and organic synthesis. The laboratory is located in the Joseph Priestley building, in the Mile End campus of Queen Mary University, a beautiful area next to Mile End and Victoria parks in the heart of East London.

Eligibility and Applying

Prospective students must be eligible for a China Scholarship Council PhD scholarship (i.e. Chinese nationals with at least an upper second class degree in Chemistry or a related discipline), and the position is subject to successfully securing the scholarship. The applicant should have knowledge of organic and/or organometallic chemistry as well as good interpersonal and communication skills. 

For informal enquires please contact Dr Xacobe Cambeiro (x.cambeiro@qmul.ac.uk). For formal applications, please submit an online application before the stated deadline.
