To provide insight into the reactive chemistry of selected organometallic species and to outline the underlying principles of structure and bonding.
After studying the unit, students should be able to:
* Describe the basic metal ligand bonding interactions in metal π-complexes (C2, C3, C4, C5, C6, C7, C8 systems).
* Use the DGM rules to predict and rationalise the reactivity of 18-electron complexes bearing hydrocarbon ligands
* Rationalise the reaction of electrophiles with π-complexes
* Critically assess methods of synthesis and reactivities of organometallic systems
* Critically assess and rationalise the synthesis and reactivity of low nuclearity transition metal clusters
* Rationalise the isolobal principle, and apply it
* Critically assess recent literature examples of organometallic and transition metal clusters chemistry and suggest synthetic routes to designed materials with specific functionalities and/or properties
* Describe the role of organometallics in catalysis.
Numeracy (F, A), Problem solving (T, F, A), Scientific writing (f, A), Independent working (F), Group working (F).
The unit will provide insight to selected aspects of advanced organometallic chemistry. An overview of the bonding and reactivity of metal carbon σ,π acceptor ligands will be given. The unit will build on the concepts of the 18 electron rule and metal-metal bonding and introduce aspects of transition metal cluster chemistry (esp. synthesis, structure, bonding and reactivity). Introduction to the isolobal principle will introduce be used to develop concepts and ideas in metal-metal bonded and metal-carbon (element) multiple bonded systems (e.g. metal carbenes carbines, and higher metal cumulenes). The unit will describe the role of organometallic species in catalysis for selected examples.
