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.
