As a common heterocyclic compound, it belongs to ruthenium-catalysts compound, name is Dichlorotris(triphenylphosphino)ruthenium (II), and cas is 15529-49-4, its synthesis route is as follows.
Add 1a (0.600g, 3.44mmol) under nitrogen protection In a 100mL three-neck bottle, Additional tris(triphenylphosphine) ruthenium dichloride (2.50 g, 2.61 mmol) and 40.0 mL of tetrahydrofuran, Stir and dissolve, then add acetyl chloride (0.22 mL, 3.13 mmol). After the addition, the mixture was heated to 73 C (external temperature: 83 C), and the reaction was stirred for 3 hours to stop the reaction. The reaction solution was concentrated under reduced pressure at 40 C. Add isopropanol / petroleum ether (1.0 mL / 20.0 mL) and stir to precipitate a solid. Filter and wash with a small amount of petroleum ether. After drying, 2.10 g of red ruthenium complex product 2a (93%) was obtained.
15529-49-4, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,15529-49-4 ,Dichlorotris(triphenylphosphino)ruthenium (II), other downstream synthetic routes, hurry up and to see
