Postgraduate Studentship: F-ex. F-block Hydrocarbon Interactions: Exploration; Exploitation

The University of Edinburgh - School of Chemistry

Prof. Polly L Arnold

A postgraduate studentship is available for a synthetic project on co-ordination and organometallic f-block chemistry, starting September 2018. This is a 3 year, tax-free studentship award, and covers tuition fees and living costs (approximately £14.5 k per annum) for UK and EU nationals, in line with the ERC's current recommended level.

Project:

We have used organometallic systems to study two types of poorly understood hydrocarbon interactions with f-block metal cations: arene binding which is stronger, yet controversial in terms of its electronic demands, and neutral hydrocarbon C-H bonding which is weaker, yet crucially reaction controlling.

The successful applicant will join a team, funded by the award of an ERC Advanced Grant, f-ex, working on exploratory synthetic organometallic chemistry of the f-block. The project aims are to develop new ways to experimentally measure and define these subtle hydrocarbon interactions, and to exploit the stored electrons in the metal-arene motif as a new method to control these powerful Lewis acidic metals for small molecule activation and hydrocarbon C-H bond cleavage, with the ultimate aim of viable, low-energy, catalytic small molecule functionalisations.

Applications:

No previous experience of f-block chemistry is necessary, but applicants with a strong interest in synthetic, air-sensitive inorganic synthesis will be welcomed. Applicants should hold, or expect to receive, a 2(i) or first-class Honours degree (or equivalent) in chemistry.
