Unit code: CHEM61521
Credit Rating: 15
Unit level: Level 6
Teaching period(s): Semester 1

Aims

  • Emphasize aspects of core inorganic chemistry that are essential to the study of organometallic complexes and their reactivity.
  • Introduce topics in advanced concepts of structure, bonding and reaction mechanisms in organometallic chemistry including: organometallic reagents in synthesis, homogeneous catalysis by organometallic complexes, reactions of coordinated ligands.
  • Show how ligand design and synthesis is vital in modern coordination chemistry and can be used to direct structures.
  • Provide an introduction to, and a general overview of, the chemistry and physical properties of the f-block elements.
  • Acquire standard techniques in synthetic  organometallic chemistry: use of non-aqueous solvents, inert atmospheres, column chromatography.
