Anotace
This course will familiarize students with the basics of transition metal chemistry (formalisms, electron counting, and bonding) and provide a practical introduction to the mechanisms of organometallic reactions. The chemistry of pi‐alkylmetal complexes, and transition metal alkene, alkyne, arene, diene, and dienyl complexes will be presented and discussed.
The importance of transition metal‐promoted bond‐forming processes in organic synthesis will be illustrated with examples from the contemporary literature and applications to the synthesis of natural products.
