A new carbene ruthenium complex 1,3-bis(2,6-dimethylphenyl)4,5- dihydroimidazol -2- ylidene)(PPh3)(Cl)2Ru=CHPh was synthesized and used as catalyst for the metathesis of 1-hexene. The resulting complex exhibited very high catalytic activity of up to turn of frequency of 6680 h-1, but along with significant olefin isomerization, which could be surpressed by changing reaction conditions, such as temperature, time, alkene/Ru molar ratio and solvent.
