Method for Preparation of a Ruthenium Indenylidene Complex |
摘要 |
The present invention is directed to a method for the preparation of ruthenium catalyst (PCy3)2Cl2Ru(phenylindenylidene) (Umicore catalyst “M1”). The method comprises a one-step reaction reacting the precursor compound (PPh3)2Cl2Ru(3-phenylindenylidene) with PCy3 in a cyclic ether solvent (preferably THF) in concentrations in the range of 0.2 to 0.6 mol catalyst/l while simultaneously precipitating the product from the reaction mixture.;A cyclic ether solvate product with high crystallinity and high purity is obtained. |

1. A method for preparation of the ruthenium-indenylidene carbene catalyst of Formula 1, said method comprising
reacting (PPh3)2Cl2Ru(3-phenylindenylidene) with tricyclohexyl-phosphine (PCy3) in a reaction mixture having a concentration in the range of 0.2 to 0.6 mol Ru-catalyst/l in a cyclic ether solvent andprecipitating the resulting catalyst of Formula 1 during the reaction. |
