Abstract:
Cross-coupling methodology is an indispensable part of the everyday repertoire of synthetic organic chemists. bonds1,2); a mechanistic scheme for this transformation is shown below. This methodology has been widely utilized throughout academia and industry.
This lecture will include:
- An introduction to palladium-catalyzed carbon-heteroatom bond-forming reactions including an historical overview.
- A description of ligand and precatalyst development employing biarylphosphines.
- Applications of these catalysts to the preparation of compounds of interest to medicinal chemists.
- Examples of the use of Pd complexes for the selective functionalization of large molecules.
- If time permits, some of our recent development of Cu catalysts for C-heteroatom bond formation.
