Technology Process of ReH₃{PMe₂Ph}4

There total 6 articles about ReH₃{PMe₂Ph}4 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: 80.0%

sodium tetrahydroborate (16940-66-2) + Re(PMe2Ph)3Cl3 (15613-32-8) + Dimethyl(phenyl)phosphine (672-66-2) → ReH3{PMe2Ph}4 (79245-24-2)

Guidance literature:

In ethanol; solution of Re(PMe2Ph)3Cl3 in degassed abs. ethanol, addn. of PMe2Ph and NaBH4, heated to reflux under nitrogen, 3 h; cooled down to 25° C, solvent removed under vacuum, semisolid dissolved in hot hexane, cooled to room temp., filtration, drying under vacuum;

Reference yield: 50.0%

cis-hydrido(dinitrogen)tetrakis(dimethylphenylphosphine)rhenium(I) (135707-77-6) + malonic acid dimethyl ester (108-59-8) → ReH3{PMe2Ph}4 (79245-24-2) + Re(P(CH3)2C6H5)4(CH3OOCCHCOOCH3) (215875-18-6)
