Group 10 metal complexes with redox-active pincer ligands: electronic structure and reactivity

The continuing interest in pincer ligands is due to their unique ability to modify the properties of metal centers and thus the properties of the complexes they form. Using these ligands, one can finely tune the electronic and steric properties of the metal center. Moreover, the possibility to perform the redox process directly on the pincer ligand expands the range of applications of complexes based on them. The aim of this review is to analyze the state of the art in research into complexes of Group 10 metals (nickel, palladium, platinum) with redox-active pincer ligands. A brief introduction to the methods of investigation and modification of the electronic structure of the complexes is presented. The fundamental stoichiometric reactivity and relevant catalytic applications of the title systems are considered.
