CH30162: Advanced organometallic chemistry
|Supplementary Assessment:||Like-for-like reassessment (where allowed by programme regulations)|
|Requisites:||Before taking this unit you must (take CH10133 and take CH20147) or (take CH10134 and take CH20148)|
To provide insight into the reactive chemistry of selected organometallic species and to outline the underlying principles of structure and bonding. To introduce the topic of low oxidation state transition metal clusters.
After studying the unit, students should be able to:
* Describe the simple metal ligand bonding interactions in metal π-complexes
* Predict the reactivity of 18-electron complexes bearing hydrocarbon ligands.
* Give examples of reactions of organometallic complexes with electrophiles and nucleophiles
* Predict the metal framework structure of transition metal clusters.
* Outline the general synthetic techniques involved in the synthesis of low nuclearity transition metal clusters.
* Describe the isolobal principle.
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 donor /π acceptor ligands will be given and the chemistry of metal polyene complexes and their reactivity (Davies-Green-Mingos rules) will also be introduced. 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 carbynes, and higher metal cumulenes).
