The course unit unit aims to:
- Provide an overview of advanced topics in organometallic chemistry including fundamental aspects of structure and bonding and applications in organic synthesis and catalysis.
- Highlight current applications of this technology in the synthesis of bioactive molecules.
- Emphasise aspects of core inorganic and organic chemistry that are essential to the study of organometallic complexes and their reactivity.
- Illustrate the importance of this topic in contemporary research and development.
Students should note that this course is taught by members of staff from the Inorganic and Organic Teaching groups (Dr Mair 33%; Prof. Greaney 33%; Prof Larrosa 33%). The course covers different material than is covered within CHEM30311.
- Brief revision of topics covered previously within the curriculum.
- Metal alkyl synthesis and reactivity.
- Applications of main group metal complexes, especially organolithium complexes, to organic synthesis.
- Directed metallation of organic substrates using organolithiums.
- Limited aspects of organotitanium and organocuprate chemistry.
- The breakdown of transition metal alkyl complexes, including reductive elimination and -hydrogen elimination.
- Transition metal coupling chemistry (including Heck, Negishi, Hartwig-Buchwald and Susuki coupling).
- -Complexation: metal-alkene and metal-alkyne complexes.
- Alkyne-vinylidene rearrangements.
- Alkyne polymerization and higher order cycloadditions.
- -Allyl complexes: structure and bonding and application to organic synthesis.
- Structure and bonding in Fischer/Schrock Carbene complexes.
- Preparation of Carbene complexes.
- Use of carbene complexes in synthesis: Group 6 TM carbenes (Stoichiometric: Dotz chemistry etc) ii. Catalytic processes (as exemplified by the use of Cu, Rh, Ru complexes) iii. acetylene-vinylidene rearrangements and related reactions.
