Drastic Acceleration of Phosphine/Phosphite Incorporation into a Tetrahydrido Ruthenium/Osmium Complex, and One-way Ruthenium to Osmium Migration of a Phosphorus Ligand

摘要

Cluster complexes form an attractive class in the reactions of transition metal complexes, owing to their capability of activating substrates effectively through the cooperative effects of multiple metal centers. To date, we have demonstrated several examples of cooperative activation by treating various substrates, including unsaturated hydrocarbons, with [Cp~*Ru(μ-H)4RuCp~*] (1, Cp~* = η~5-C5Me5) and [(Cp~*Ru)3(μ-H)3(μ3-H)2].
