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.
cis-cis- 1,3,5-triaminocyclohexane (30.0 nig, 0.232 mmol) was added to an ampoule charged with dichlorotris(triphenylphosphane)ruthenium(II) (196 mg, 0.204 mmol) dissolved in dichloromethane (20 mL), causing an instant colour change from black to orange. The solution was stirred at 50C for 4 days in the sealed vessel, during whichtime the solution changed colour to yellow and a white precipitate formed. The precipitate was removed by filtration and the filtrate reduced in volume to approx. 1 mL in vacuo. The product was precipitated by addition of pentane (20 mL) as an orange powder, and washed twice with pentane (20 mL). Yield: 115 mg (86.8 %, 0.177 mmol of RuCl2(K3-c -tach)(PPh3).CH2Cl2).
