In recent years, there has been a growing interest to investigate catalytic systems that exhibit cooperative effects. Many studies have been performed in order to develop multinuclear, catalytically active complexes, in which the metal atoms act cooperatively to form the desired product, controlling both the observed activity and selectivity. The use of redox non-innocent ligands, the ability to activate the substrate by a ligand-metal bifunctional mechanism and the presence of metal-metal interactions, among others, have been recognised as useful strategies for the design of catalysts that might exhibit cooperative effects. However, it is widely accepted that the rational synthesis of such systems is still in its infancy, since the underlying fundamental interactions between the metal centres are not fully understood. Nevertheless, some studies have been contributed in recent years in order to shed some light upon the mechanisms that give origin to cooperative effects in catalysis.<sup> </sup>Furthermore, cooperative effects in multinuclear complexes featuring redox-switchable metalloligands have been observed. In this regard, we have employed “tailor-made” ambidentate ligands for the synthesis of heterodinuclear complexes featuring a redox-active spectator entity and the catalytically active metal centre in the same region of space. In this oral presentation, our recent efforts in exploring these and related types of complexes will be presented.
