- Abstract
- Areas ranging from fine chemical synthesis to sustainable energy development rely on highly efficient metal-based catalysts to perform key chemical transformations [1]. Then metals such as Pd, Pt, Rh, Ir or Ru are used because they are proficient at mediating the multi-electron transfer steps required for these applications. In contrast to synthetic chemistry, biological systems do not use noble metals but rather employ cooperative reactivity between multiple redox sites [2]. These sites store and provide additional electrons to avoid unfavorable oxidation states at the reactive centers. Replicating this strategy of redox cooperativity in synthetic complexes could offer a valuable way to enhance the reactivity of base metal catalysts like iron, copper, etc. Such kind of systems have already been developed by Rauchfuss et al. to mimic Fe-Fe hydrogenase [3] and Bosnich and co-workers placed the basics for understanding bimetallic systems [4]. However, increase the comprehension of incorporating and controlling the additional redox centers is still a major challenge. Here, we planned to develop new bimetallic complexes where the two metals will be in a close proximity thanks to a ditopic ligand and then, to better understand the cooperativity between the metal centers and highlight the importance of the ligands design.
