| 摘 要： | A new carbene ruthenium complex, 1,3-bis（2,6-dimethylphenyl）-4,5-dihydroimidazol-2-ylidene）（PPh3）Cl2-Ru=CHPh, was synthesized and used as catalyst for the metathesis of 1-hexene. The resulting complex exhibited very high catalytic activity whose TOF is up to 6680 h^-1. However, at the same time significant olefin isomerization was observed and could be surpressed by changing reaction conditions, such as temperature, time, alkene/Ru molar ratio and solvent.

| Abstract: | A new carbene ruthenium complex, 1,3‐bis(2,6‐dimethylphenyl)‐4,5‐dihydroimidazol‐2‐ylidene)(PPh3)Cl2‐Ru=CHPh, was synthesized and used as catalyst for the metathesis of 1‐hexene. The resulting complex exhibited very high catalytic activity whose TOF is up to 6680 h?1. However, at the same time significant olefin isomerization was observed and could be surpressed by changing reaction conditions, such as temperature, time, alkene/Ru molar ratio and solvent. |
