New Approaches in Catalytic Reactions Using Triphos: A Classical Privileged Ligand |

Over the past decades multiple catalytic transformations have been feasible due to the application of triphos as ligand. Its particular fac coordination mode to a transition metal center provides a suitable flexibility enabling variation on the coordination mode resulting in metal stabilization. Most of the reported catalytic reactions have been dominated by the use of the ruthenium-triphos system, either by application of well-defined complexes or the in situ formed complex. However, in the last years the emergence of cobalt complexes with comparable or even superior catalytic performance than ruthenium have been reported. In this review we have focused on the use of triphos in selected reactions such as N-alkylation, formic acid dehydrogenation and bond cleavage.
