Throughout the 2021-22 academic year, we will be prioritising face to face teaching as part of a blended learning approach that builds on the lessons learned over the course of the Coronavirus pandemic. Teaching will vary between online and on-campus delivery through the year, and you should read guidance from the academic department for details of how this will work for a particular module. You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.

Module aims

The module aims to give an advanced background to the issues which impact on industrial catalytic reactions. Organometallic chemistry uses principles from organic and inorganic (particularly coordination) chemistry, and also physical chemistry (particularly kinetics). Inorganic materials chemistry uses principles from inorganic chemistry (structures of solids) and physical chemistry (electronic properties of solids). The module draws together aspects of this work developed in Year 2 and extends it to the types of reactions and catalysis used widely in chemical industries (petrochemicals, polymers, fine chemicals and pharmaceuticals).

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Introduction
What is catalysis? Homogeneous vs Heterogeneous. Key concepts
Recap: Electron Counting and Coordination Numbers in Organometallics; Covalent Bond Classification
Reactivity of organometallics: Oxidative addition and Reductive Elimination
Reactivity of organometallics: Insertion and Elimination

Homogeneous Catalysis

  • Hydrogenation
    Activation of dihydrogen using transition metals
    Mechanisms of alkene hydrogenation
    Mechanisms of ketone hydrogenation (including transfer hydrogenation)
    Asymmetric hydrogenation
    Homogeneous vs. Heterogeneous catalysis (arene hydrogenation)
  • Hydroformylation of alkenes (Co, Rh)
  • Hydrocyanation (Ni)
  • Carbonylation of methanol (Rh, Ir)
  • Carbonylation of alkynes (Ni)
  • Wacker Process (Pd)
  • Heck olefination (Pd)
  • Olefin metathesis (Co, Mo, pre Grubbs)

Heterogeneous Catalysis

  • Zeolites: silicates and alumino-silicates
    Structure description
    Synthesis: solvothermal crystallisation
    the use of templates
    design of new materials
  • Zeotypes: AlPOs
  • Mixed tetrahedral-octahedral frameworks (transition-metal-containing)
  • Mesoporous silicas
  • Metal-Organic Frameworks: structures and synthesis
  • Ion-exchange properties of nanoporous materials
  • Separation (molecular sieving) by porous materials
  • Shape-selective catalysis:
    Petroleum cracking
    Solid-acid catalysis
    Transition-metal containing microporous catalysts for oxidation
    Mesoporous solids to tether molecular catalysts
    MOFs – limitations on their use
  • Other industrially relevant solid-state catalysts: for example, three-way catalytic convertors, Haber-Bosch, water-gas shift (WGS) reaction, steam reforming, sulphuric acid production

Summary

Learning outcomes

By the end of the module, students should be able to:

  • Apply and understand the limitations of the 18 electron counting rule in rationalising the stability of organometallic complexes by consideration of other properties of the constituent metal and ligands (sterics, coordination number).
  • Calculate and interpret the changes in oxidation state, coordination number and valence electron count during elementary reactions and use these to predict outcomes
  • For each of the organometallic reaction classes in Syllabus): Understand the mechanistic basis (using e.g. frontier MO descriptions); Recognise the situations (structure, electron count, coordination number, steric/strain) in which the reaction may occur or is promoted/suppressed; Interpret trends in given mechanistic data (i.e. reaction outcomes: rate, structure/reactivity, stability, product distribution, stereochemistry) in terms of the above; Predict the effects of designed changes of complex properties (coordination number, ligand size, charge, electron density, electron count) on reaction outcomes; Suggest & justify modifications to systems in order to effect changes in reaction outcome; Design and interpret chemical and isotopic labelling, and other mechanistic probe experiments.
  • For a range of catalytic processes mediated by organometallics (see Syllabus): Identify the fundamental reactions involved and apply; Apply the principles developed above in interpreting, predicting and designing catalytic the outcomes of catalytic reactions; Identify rate-determining and selectivity-determining steps using kinetic and reaction outcome data; Recognise off-cycle processes (such as co-catalytic cycles, decompositions, equilibria)
  • Describe the structures of microporous zeolites in terms of primary and secondary building units using the examples of sodalite, zeolite A and zeolite X/Y.
  • Describe the structures of microporous phosphates and mixed polyhedral frameworks in relation to zeolites.
  • Understand the role of templating in the synthesis of mesoporous solids.
  • Describe the structures of metal organic frameworks
  • Predict conditions details for porous solids in terms of choice of reagents on the product of reaction
  • Rationalise unseen experimental data concerning the uses of porous solids in catalysis, including the following features of their reactivity: Shape-selective adsorption (molecular sieving); Solid-acid catalysis; Transition metal redox catalysis; Ion-exchange
  • Rationalise unseen experimental data concerning the uses of transition-metal oxides in heterogeneous catalysis, with reference to their redox activity.
  • Design synthetic experiments on the basis of input from laboratory scripts, literature sources, previous experiments and advice from demonstrators.
  • Understand and assess the spectroscopic etc. properties of new or unknown inorganic coordination compounds in relation to their identity, purity and physico-chemical properties as appropriate.
  • Present the results of their studies, including aspects of research work in a laboratory report for the experimental work.
