发明名称 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.
