1. Transition metal-catalyzed allylic and vinylic functionalization : Method development and mechanistic investigations
Sammanfattning : The use of small molecule building blocks in, for example, pharmaceutical research and new material development, creates a need for new and improved organic synthesis methods. The use of transition metals as mediators and catalysts opens up new reaction pathways that have made the synthesis of completely new compounds possible as well as greatly improved the synthetic routes to known compounds.
