Among the various strategies that can be used to design powerful catalytic systems, the access to well-defined unsaturated metal fragments is an important parameter. The choice of ligands in the coordination sphere of a metal is thus important, and for example, pincer-type ligands have proven to be remarkable at generating a series of unsaturated metal complexes, and have been successfully exploited in catalysis.1 The use of labile ligands such as dihydrogen, on the other hand, produces similarly highly unsaturated metal fragments.2 Some of the latest results from our group will be presented to demonstrate their application in domains ranging from hydrogenation/dehydrogenation, H/D exchange and CO2 functionalization.J.
