主 题:Ruthenium carbene metathesis.
摘 要:A kinetic study of two ruthenium carbene catalysts, (PCy3)2Cl2Ru=CHPh 1 (Grubbs catalyst) and a new catalyst [1,3-bis(2,6-dimethylphenyl)4,5-dihydroimidazol-2-ylidene](PPh3) (Cl)2Ru-CHPh 3, were conducted in metathesis of 1-hexene. The kinetic behavior of these catalysts at 40, 50, 60 and 70℃ was compared. Complex 3 has the more active catalytic effect at temperatures 40-70℃.
