Course Materials

This page contains links to most of the handout material you have been provided with in class. In cases where the material was sourced from the web, the original links are provided; class versions are usually an abbreviated form. Notes are not reproduced here; if you have missed lectures, you will need to obtain these off a classmate. Most of the files here are in pdf format ().

• MS and EPR (); isotope patterns, reaction tracking, EPR spectrum.
• Proton NMR (); coupling patterns, coordination shifts, and stereochemical non-rigidity.
• Metallocene catalysts () for olefin polymerisation, and a catalytic cycle for the Wacker Process.
• Olefin metathesis (). The figures for this handout came from a rather good C&EN article entitled "Olefin metathesis: big deal reaction". More background information is available in a sister article, "Olefin Metathesis: the Early Days".
• Chauvin, Grubbs & Schrock won the 2005 Nobel Prize for Chemistry.
• Catalytic cycles for hydroformylation and hydrocyanation (). Accessible background reading on asymmetric hydrogenation can be found in the Nobel lectures of Knowles and Noyori (2001).
• The 12 principles of green chemistry.
• Catalytic cycles for hydroformylation and hydrocyanation ().
• Major differences between homogeneous and heterogeneous catalysts ().
• Homogeneous catalysis - reaction profile and catalytic cycle ().
• Arene ligand reactivity, nucleophilic abstraction ().
• Insertion, nucleophilic attack schemes ().
• Oxidative addition and reductive elimination ().
• Chem324 notes on the trans effect and ligand substitution (parts 1 and 2).
• A recent and readable Nature review on NHCs ().
• Geoffrey Wilkinson's Nobel Lecture, "The Long Search for Stable Transition Metal Alkyls" () (also published in Science 1974, 185, 109). Note the lack of mention of Lappert...
• The original Davies-Green-Mingos rules paper ().
• Selected reactions () of ferrocene and the pi-molecular orbitals of benzene.
• Structures of various hydrocarbon pi-ligands ().
• The Organometallic Hypertextbook has an MO diagram for ferrocene.
• Bonding () in dihydrogen, alkene and buta-1,3-diene complexes.
• Metal hydrides () - synthesis, bridging hydrides, Kubas' dihydrogen complex.
• Phosphines () - Tolman cone angle, chiral phosphines, phosphine immobilisation. See ball-and-stick models of different phosphines.
• Binary carbonyls () - some properties and structures.
• The Organometallic Hypertextbook covers electron counting in detail.
• Molecular orbital diagrams () for octahedral complexes.
• Electron counts () for some commonly encountered ligands.
• Structures of some unusual organometallic compounds ().
• Periodic Table. Reproduced (though often with small inaccuracies) in nearly all chemistry textbooks and many versions are available on the net. I recommend Mark Winter's Printable Periodic Table (); this is the PT you will be provided with in midterms and for the final exam.
