15529-49-4, Dichlorotris(triphenylphosphino)ruthenium (II) is a ruthenium-catalysts compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: The same basic method, as described here for [RuCl(PPh3)2(LMe,H)]Cl, was followed for all the complexes in this study. Asuspension of [RuCl2(PPh3)3] (0.36 g, 0.4 mmol) and LMe,H (0.15 g,0.4 mmol) in dry dichloromethane (15 cm3) was stirred for 3 h atroom temperature. This yielded an orange precipitate, which wascollected by filtration. Alternatively, the products 3-6 were solublein the reaction mixture, and were precipitated from it by careful addition of diethyl ether. In either case, the resultant solids werewashed repeatedly with diethyl ether to remove excess PPh3, thendried in vacuo.

The synthetic route of 15529-49-4 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15529-49-4,Dichlorotris(triphenylphosphino)ruthenium (II),as a common compound, the synthetic route is as follows.

Example B2: Preparation of [(CI)2Ru(Pphenyl3)(ligand L2)], K2tolueneyl 272.5 mg (0.284 mmol) of dichlorotris(triphenylphosphine)ruthenium(ll) and 160.0 mg (0.296 mmol) of ligand L2 are placed in a 10 ml Schlenk tube and admixed with 6.5 ml of dry toluene under argon. The dark suspension is stirred overnight at room temperature, resulting in a colour change to orange-red. After addition of 4 ml of dry pentane, the stirrer is switched off and the supernatant orange solution is filtered off with suction from the orange solid. The solid is washed five times with 4 ml each time of pentane and dried in a high vacuum. This gives 244 mg (88% of theory) of the title compound as an orange powder. 31P-NMR (C6D6, 121.5 MHz, ppm): 49.7 (d, J = 40), 61.2 (d, J = 40).

As the paragraph descriping shows that 15529-49-4 is playing an increasingly important role.

RuCl2(PPh3)3(480 mg, 0.5 mmol) was placed in a 25 mL flask filled with argon. THF(12.5 mL) and (R,R)-DPEN (127 mg, 0.6 mmol) were then added. The mixturewas degassed and stirred under argon at 25 oC for 6 h. After removalof turbidity by filtration, n-hexane (30 mL) was added, and a light yellowsolid was obtained. The supernatant was removed and the resulting solid wasdried under reduced pressure to give analytically pure 1f (442 mg, 97% yield). 2.1.

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).
