Résumé : Critical to the development of catalysts with practical potential in synthetic chemistry is a fundamental understanding of the mechanistic features which lead to a robust and selective catalytic system. Within this regard, our group has focused on the development of new palladium catalysts for various oxidation and cross-coupling reactions wherein mechanistic analysis has played a vital role in catalyst and reaction design. This presentation will focus on our recent efforts to design new reactions with a particular emphasis of redox-relay enantioselective Heck reactions,wherein exquisite control of migratory insertion and β-hydride elimination is required for a successful outcome.
