"Privilege ligands design based in a donor backbone"

Catalysis is the most powerful tool in organic synthesis, for this reason, almost 70% of compounds used in our daily lives are prepared using at least, a catalytic step in their obtainment. Nowadays, the design and synthesis of new catalysts is an area in constant development and is focused on improving processes, to avoid special reaction conditions, such as, the use of inert atmosphere, deoxygenation, or dryness conditions. For this reason, researchers in all around the world hard working in design and development of modular ligands to synthesize catalytic precursors capable to achieve a quite range of catalytic applications. These privileged ligands, normally possess a rigid structure with different functional groups to bind strongly to reactive metal center as well as generate a highly active and selective catalytic system.

In this seminar, we will discuss about the design and synthesis of novel bidentate ligands. These catalytic precursors have been used in different carbon-carbon coupling reactions in a microwave enhanced protocol, catalytic hydrogen transfer, asymmetric allylic alkylation, C-H direct functionalization of arenes, among others. Additionally, some complexes work well in presence of moisture and oxygen with high TON and TOF values.
