Effects of Halides and Related Ligands on Reactions of Carbonylruthenium Complexes (Ru0–RuII)

摘要: While the primary motivation of fundamental studies on carbonylhalotriruthenium complexes was to understand promoter effect halides certain ruthenium-based catalytic systems industrial relevance, such have gained significance in their own right due remarkable ability provide low-activation energy pathways for coordination organic substrates. Limitations inherent fragility these prototypes led design and development a related family more sophisticated derivatives where an aminopyridyl group serves as alternate hemilabile ancillary ligand. Studies reactivity revealed possibility achieving number stoichiometric or moderately “cluster-mediated” transformations substrates under very mild conditions. Yet, viability is still limited narrow low-energy domain. By contrast, halotriruthenium are seen function catalyst precursors actual conditions reactions they act sources ruthenium(II) halide that become active components system. The second part review focuses novel aspects fascinating chemistry.
