Our aim is to deepen in the knowledge of the metal-σ bond interactions, determining the chemical nature of the different species found, its relationship with the kind of rupture of the bonds and its application to the development of processes and materials of interest for society. The interaction of H-H, B-H, C-H, Si-H, N-H, O-H, C-C and C-halogen bonds with the metallic center of a variety of metal precursors of the groups 8 and 9 is  being studied. The generated knowledge is used for the development of catalysts for the reversible dehydrogenation of amine-boranes and liquid organic hydrogen carriers (cyclic amines and alcohols), efficient catalytic methods by the reductive dehalogenation of persistent organic contaminants (POCs), new dopants for PHOLEDs with high efficient emissions in the high energy region and efficient catalytic procedures, and catalysts, for the borylation of organic molecules.
