Abstract

Catalysis allows for increased levels of selectivity and efficacy of chemical transformations and can thus be seen as an important, environmentally friendly technology. The field of C-H bond activation chemistry is rapidly developing, holding the promise to be transformative for chemical synthesis at one point. In this talk, recent results in the field of C-H activation developed by the Glorius group will be presented, especially based on Rh(III) and Co(III) catalyst systems. Some (increasingly) important trends can be identified: mild transformations, non-chelate assisted (undirected) C-H activations and C-H activations for the efficient formation of heterocycles. In addition, heterogenous catalyst systems (such as Pd/C) might offer unique opportunities for selective and practical C-H functionalization.

In addition, asymmetric arene hydrogenation using a Ru-N-heterocyclic carbene (NHC) complex will be presented. Impressively, 8 different substrate classes could be successfully reduced using this privileged catalyst. A few comments will also be made on intermolecular reaction screening, allowing the rapid assessment of chemical reactions.
