Abstract:
Different homogeneous ruthenium catalysts such as the Grubbs-Herrmann- (RuCl2(1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazolin-2-ylidene)(=CHPh)(PCy3)) and the Grubbs-Hoveyda-catalyst (RuCl2(=CH(2-(2-PrO-C6H4)(1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazolin-2-ylidene)) were modified through chlorine exchange in reactivity and selectivity. The activity in olefin-metathesis could be improved. Exchange with CF3COOAg on the Hoveyda-Grubbs-catalyst provided the first time a catalyst active f...     »

Hierbei konnte die Katalysatoraktivität in der Olefin-metathese deutlich erhöht werden. Durch Umsetzung von CF3COOAg mit dem Hoveyda-...     »
