Name is Dichlorotris(triphenylphosphino)ruthenium (II), as a common heterocyclic compound, it belongs to ruthenium-catalysts compound, and cas is 15529-49-4, its synthesis route is as follows.
An anhydrous Et2NH (10 mL) solution of dicyclohexylphosphinomethylpyridine-borane complex (280 mg, 0.923 mmol) was heated at 65C for 48 h under Ar. The solution was cooled to room temperature and Et2NH was removed in vacuo (ca. 10 mmHg, room temperature). To the residue was added sequentially dichlorotris(triphenylphosphino)ruthenium (II) (442.5 mg, 0.46 mmol) and an anhydrous toluene (10 mL). The resulting mixture was heated at 110C for 5 h under Ar, and was cooled to room temperature. Then to the mixture was added an anhydrous hexane (20 mL) to afford the yellow suspension. The mixture of the suspension was stirred at room temperature for 12 h and filtered through a filtration paper. The obtained yellowish orange solid was dried in vacuo (ca. 0.1 mmHg, room temperature) and dissolved in CH2Cl2. This solution was purified by column chromatography on silica gel (EtOAc/hexane =1/4) to afford RUPCY (1a) as orange powder (237 mg, 68%).
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
