A Stable Ruthenium Catalyst for Productive Olefin Metathesis
摘要:
New ruthenium carbene complexes 5 and 6, containing a rigid bicyclic phosphine moiety, have been prepared, and the structure of 5 has been unambiguously established by single-crystal X-ray diffraction studies. These ruthenium-based complexes show excellent stability to air and moisture, can be recycled by chromatography, and are available from simple precursors. They are efficient catalysts for various metathesis reactions, particularly for applications where high selectivity is required.

phoban-indenylidene complex is a robust catalyst for self-metathesis and ethenolysis reactions of methyl oleate. The phoban-indenylidene catalyst was characterized by X-ray analysis, NMR and microanalysis and was used in various self-metathesis and ethenolysis of methyl oleate, giving rise to significantly higher end of run conversions compared to Grubbs 1st generation catalyst. These complexes are more stable

The invention is directed to ruthenium-based metathesis catalysts of the Hoveyda-Grubbs type. The new N-chelating diarylamino-based ruthenium catalysts described herein are stable in solid state and in solution and reveal rapid initiation behavior. Further, the corresponding N-substituted styrene precursor compounds are disclosed. The catalysts are prepared in a cross-metathesis reaction starting from N-substituted styrene precursors. The new Hoveyda-Grubbs type catalysts are suitable to catalyze ring- closing metathesis (RCM), cross metathesis (CM) and ring-opening metathesis polymerization (ROMP). Low catalyst loadings are sufficient to convert a wide range of substrates via metathesis reactions.

The invention is directed to ruthenium-based metathesis catalysts of the Grubbs-Hoveyda type. The new 2-aryloxy-substituted ruthenium catalysts described herein reveal rapid initiation behavior. Further, the corresponding styrene-based precursor compounds are disclosed. The catalysts are prepared in a cross-metathesis reaction starting from styrene-based precursors which can be prepared in a cost- effective manner. The new Grubbs-Hoveyda type catalysts are suitable to catalyze ring- closing metathesis (RCM), cross metathesis (CM) and ring- opening metathesis polymerization (ROMP). Low catalyst loadings are necessary to convert a wide range of substrates including more complex and critical substrates via metathesis reactions at low to moderate temperatures in high yields within short reaction times.
