Technology Process of cis-Dichlorobis(2,2'-bipyrazyl)ruthenium(II)

There total 7 articles about cis-Dichlorobis(2,2'-bipyrazyl)ruthenium(II) which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 82.0%

{Ru(2,2'-bipyrazine)2(CH3CN)Cl}(PF6) (80907-58-0) + tetraethylammonium chloride (56-34-8) → ruthenium(2,2'-bipyrazine)2Cl2 (80907-59-1)

Guidance literature:

In acetonitrile; Irradiation (UV/VIS); soln. of Ru complex was stirred and irradiated (3500 ?), then added (Et4N)Cl soln. in acetonitrile and irradn. continued for 23 h; mixt. was evapd., residue dissolved in propanol and pptd. with ether; residue was filtered out and washed with ether, then acetonitrile; identified by cyclovoltammetry; elem. anal.;

Reference yield: 67.0%

tris(2,2′-bipyrazine-N1,N1′)ruthenium(II) hexafluorophosphate + tetraethylammonium chloride (56-34-8) → ruthenium(2,2'-bipyrazine)2Cl2 (80907-59-1) + {Ru(2,2'-bipyrazine)2(CH3CN)Cl}(PF6) (80907-58-0)

Guidance literature:

With acetonitrile; In acetonitrile; Irradiation (UV/VIS); soln. of Ru complex was irradiated (3500 ?) for 5 min, then added (Et4N)Cl soln. in acetonitrile and irradn. continued for 8 h at 40°C; react. was monitored by UV, when 610 nm peak was only a small shoulder, mixt. was evapd. to dryness.; residue was washed with propanol and ether, dissolved in acetone, evaptd., filtered off, ppt. dissolved in acetonitrile, products were sepd. by chromy. (Sephadex LH-60); Ru acetonitrile complex was pptd. with ether; elem. anal.;

Reference yield: 44.0%
