15529-49-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Dichlorotris(triphenylphosphino)ruthenium (II), cas is 15529-49-4,the ruthenium-catalysts compound, it is a common compound, a new synthetic route is introduced below.

General procedure: Diphosphine ligand (2.0 mmol) was dissolved in 10 mL of dichloromethane and the solution was added dropwise to a stirred solution of RuCl2(PPh3)3 (1.0 mmol) in 10 mL of dichloromethane. The reaction mixture was stirred approximately for 50 min at room temperature. The brown solution was filtered to remove the insoluble impurities. The solvent was reduced by a vacuum and the product was then precipitated by adding n-hexane. The yellow solid was filtered and washed three times with 20 mL of diethyl ether.
