The present invention is directed to a method for the preparation of ruthenium catalyst ( PCy3)2CI2Ru(phenylindenylidene) (Umicore catalyst "M1"). The method comprises a one-step reaction reacting the precursor compound (PPh3)2CI2Ru(3-phenylindenylidene) with PCy3 in a cyclic ether solvent (preferably THF) in concentrations in the range of 0.2 to 0.6 mol catalyst/I while simultaneously precipitating the product from the reaction mixture. A cyclic ether solvate product with high crystal linity and high purity is obtained.
该发明涉及一种用于制备
钌催化剂(PCy3)2CI2Ru(苯基
茚烯基)(优美康催化剂“M1”)的方法。该方法包括在浓度在0.2至0.6摩尔催化剂/I范围内,在
环氧化物溶剂(最好是THF)中,通过一步反应将前体化合物(PPh3)2CI2Ru(3-苯基
茚烯基)与PCy3反应,同时从反应混合物中沉淀产物。获得具有高结晶度和高纯度的
环氧化物溶剂产物。
