Chem 4620 | 7105/7100 - Homogeneous and Heterogeneous Catalysis

(GWC)2 Graduate Course and/or 4th Undergraduate Course

Next Offering

Fall 2017

Lecturer

Marcel Schlaf; MACN 314A, x 53002, mschlaf@uoguelph.ca

Objective of the course

This course will provide an introduction and overview of the field of catalysis using heterogeneous metal/metal oxide and transition metal complexes focussing on

  • general principles and reaction patterns of catalytically active transition metal centres and metal/metal oxide surfaces
  • mechanisms: kinetic and thermodynamic parameters and how to determine them
  • activation of small molecules such as hydrogen, carbon monoxide, carbon dioxide, methane, ethylene, propylene, ethylene oxide, etc.
  • large scale industrially relevant processes and their socio-economic importance

The ultimate objective of the course is to provide you with the know-how to understand (or at least make some educated guesses on) the mechanisms of any catalyzed reactions and have some insight into the principles of catalyst, reaction and process design. The course will be - as much as possible - conceptual in nature and thus should be suitable for students in any field of chemistry (inorganic, organic, physical and analytical) with 3rd year level undergraduate courses in inorganic and organic chemistry.

Time & Venue

Mondays, 1900-2130, (GWC)2 Mini-Link room, (C2-278/MACN-203)

Start: 11/09/2017

No class on 09/10/2017 (Thanksgiving)

End: 27/11//2017

Evaluation

  • Midterm 40 % (Date: 30/10/2017 - in class)
  • Presentation 30 % (06-13-20-27/11/2017 with two per session)
  • Research proposal (as take-home final) 30 % (due date 01/12/2017 by email)

Each student in the course will be required to give a 30-40 min. presentation (PowerPoint or OpenOffice/max. 30 slides) on a topic of his/her choice within the field of catalysis. In order to coordinate this effort and avoid overlap, I will suggest and discuss potential topics in the first class.

The final exam will be take-home in the form of a research proposal in NSERC format (5 pages  + 1-2 page(s) literature) on a specific topic of your choice within the field of homogeneous catalysis. The proposal and presentation cannot be on the same topic.

Guidelines on the preparation of NSERC proposals can be found on the NSERC website at www.nserc.ca.  The proposal should give a brief 2-2 1/2 pages mini-review of the (patent) literature relevant to your chosen topic and include mechanistic and/or synthetic discussion and a 2 -2 1/2 page description of the actual work to be done outlining the conceptual and experimental approach.

Tentative topics to be covered in lectures

  • What is catalysis ? Some simple truth and definitions: TOF, TON, catalyst life-times and space-time yields.
  • Homogeneous vs heterogeneous catalysts.
  • Heterogeneous catalysts: types of catalysts, active sites and defects.
  • Synthesis and characterization of metal and metal oxide catalysts.
  • Types of reactors and some important heterogeneously catalyzed processes.
  • Homogeneous catalysts: Overview of types of ligands and their electronic and steric properties. Reaction patterns of transition metal centres and their coordinated ligands.
  • The tools of the trade: mechanistic investigations through thermodynamic, kinetic and isotope labelling studies.
  • Two historical perspectives on homogeneous catalysts: The Wacker process and Wilkinson's Catalyst.
  • Hydrogenation and hydrogenolysis reactions beyond Wilkinson: The Shvo and Noyori systems: ionic and enantioselective hydrogenations.
  • Oxidation and epoxidation beyond Wacker: The search for efficient and "green" aerobic oxidation catalysts. The Sharpless catalyst.
  • Adding carbons I: Hydroformylation, hydrocyanation, carbonylation, Fischer-Tropsch chemistry and related reactions - the Monsanto process.
  • Adding carbons II: Oligomerization and dimerization reactions. The Shell Higher Olefin Process (SHOP). Metallocenes and other single-site polymerization catalysts. Metathesis reactions and ROMP using Grubb's catalyst.
  • The Holy Grail I: Catalytic C-H bond activation in simple hydrocarbons: The Catalytica process (Periana Catalyst) and related fundamental processes.
  • The holy Grail II: Catalytic Hydrodeoxygenation of biomass to fuel and chemicals.
  • Cross-coupling and other miscellaneous reactions: Heck, Stille, Sonogashira, Hartwig, Buchwald, etc.
  • Doing things differently: Ionic liquids, supercritical solvents and homogeneous catalysts on solid supports: Biphasic reactions and catalyst recovery and reuse.
