Phosphorus is essential for life on Earth and plays a prominent role in modern science and technology, where organophosphorus compounds are of immense importance for their wide-ranging applications in material science, nanotechnology and life sciences. At present, however, the overall industrial processes to produce these phosphorus compounds are unsustainable, energy intensive, and inefficient.

To meet the growing demand for phosphorus derivatives, whilst complying with increasingly stringent environmental regulations and sustainability issues, this NWO VICI research programme will advance P(III)/P(V) redox cycling and modernise the use of phosphorus by developing novel one-electron processes that minimise unnecessary redox reactions.

This interdisciplinary approach in organophosphorus chemistry exploits all facets of physical (in)organic chemistry, with a key focus on synthesis, molecular and mechanistic design, and sustainability.

In this project, we will develop:

• the controlled generation of P-radicals and their reactivity to establish novel open-shell (radical) pathways, thereby advancing P-sustainability and the eco-friendly production of benign phosphorus compounds;
• and novel redox reactions of phosphines, spent phosphine oxides, phosphoric acid and waste phosphates to enable their use as renewable feedstocks for chemicals traditionally synthesised from elemental white phosphorus (P4), which will prevent their constant spillage in the environment.

We will implement these innovations into a broader context and develop scalable protocols, which are needed to realize sustainable phosphorus chemistry on a large scale, introducing recycling, clean, and 'cradle-to-cradle' technologies as ground-breaking changes in the field to ensure the continued beneficial use of phosphorus.

The project has significant relevance for the Dutch National Research Agenda on Circular economy and resource efficiency: it will enforce a paradigm shift by developing efficient redox cycling methods to convert waste phosphates directly into high-value products using novel synthetic methodologies, and hence, contribute to modernising phosphorus chemistry by setting new frontiers.

What are you going to do

You are expected:

• To be active in the fundamental research of our sustainable main-group chemistry group, publishing in high level international journals, presenting at leading conferences and supervising BSc and MSc students;
• To study P(III) to P(V) oxidation processes to enable the design of novel, highly efficient methodologies for the production of value-added P-chemicals from alternative resources;
• To design radically new methodologies for P(V) to P(III) reduction to enable recycling and reuse of phosphorus oxides, hence, advancing P-sustainability and the eco-friendly production of key phosphorus compounds;
• Develop novel, scalable protocols for the direct, redox neutral conversion of renewable inorganic phosphates into essential and benign organophosphate products, thereby eliminating unnecessary waste at the outset

• A MSc in Molecular Chemistry;
• A strong scientific expertise in physical organic chemistry;
• Demonstrated experience in synthesis (ideally using Schlenk-line and glovebox techniques), spectroscopy, electrochemistry and computational chemistry;
• The ability and willingness to acquire all skills needed for molecular phosphorus chemistry;
• You are able to show enthusiasm and scientific rigor that meets the requirements of the project.

Your experience and profile

• Good communication skills in oral and written English;
• Takes initiative and has good time management skills;
• Interest in collaborating with students and colleagues in within and outside the institute.

A temporary contract for 38 hours per week, preferably starting in August 2022, for the duration of four years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended to a total duration of four years). This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and Masters students.

Based on a full-time contract (38 hours per week) the gross monthly salary will range from €2,443 in the first year to €3,122 (scale P) in the last year. This is exclusive 8% holiday allowance and 8.3% end-of-year bonus. A favourable tax agreement, the '30% ruling', may apply to non-Dutch applicants. The Collective Labour Agreement of Dutch Universities is applicable.

The UvA offers excellent possibilities for further professional development and education.

What else do we offer

• A function in which initiative is strongly valued;
• An enthusiastic team that welcomes new members;
• An inspiring academic and international environment in the heart of Amsterdam.

Faculty of Science

The Van 't Hoff Institute for Molecular Sciences (HIMS) is one of eight institutes of the University of Amsterdam (UvA) Faculty of Science. HIMS performs internationally recognized chemistry and molecular research, curiosity driven as well as application driven. This is done in close cooperation with the chemical, flavor & food, medical and high-tech industries. Research is organized into four themes: Analytical Chemistry, Computational Chemistry, Synthesis & Catalysis and Molecular Photonics.

The Synthetic Organic Chemistry (SOC) group is part of the Sustainable Chemistry research theme. As part of SOC and sustainable chemistry, the Slootweg group focuses on developing sustainable main-group chemistry, ideally suited to realize a circular economy. The mission of Slootweg group is to educate students at the intersection of fundamental physical organic chemistry, main-group chemistry, and circular chemistry.

Our research in this VICI project is dedicated to the development of novel and sustainable synthetic methodologies for advancing the sustainable use of phosphorus. Phosphorus compounds are essential for life on earth and play a prominent role in modern science and technology, yet their current production routes are not sustainable. This project will use P-based waste as a resource to contribute to decreasing environmental pollution and create high-value products using novel, eco-friendly methods. Therefore, we are recruiting PhD students to strengthen our research project "Enabling the Sustainable Use of Phosphorus through Novel Redox Cycling Processes".
