Technology Process of Re(hydride)(carbonyl)2(PPh₂(OEt))3

There total 1 articles about Re(hydride)(carbonyl)2(PPh₂(OEt))3 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: 40.0%

hydridopentacarbonylrhenium(I) (16457-30-0) + Ethyl diphenylphosphinite (719-80-2) → mer-cis-ReH(CO)2(PPh2OEt)3 (209606-23-5) + [ReH(CO)(P(C6H5)2(OC2H5))4]

Guidance literature:

In toluene; Irradiation (UV/VIS); (argon); irradiation (Pyrex Schlenk flask, 400 W mercury arc lamp), excess PPh2(OEt), room temp., ca. 45 h; evapn. (reduced pressure), chromy. (SiO2; light petroleum/Et2O/benzene),evapn. of the 2nd fraction, addn. of EtOH; traces of the byproduct bein g isolated from the first fraction; elem. anal.;

Reference yield: 85.0%

Re(hydride)(carbonyl)2(PPh2(OEt))3 (209606-23-5) + sodium tetraphenyl borate (143-66-8) → Re(CO)2(P(C6H5)2(OC2H5))3(1+)*B(C6H5)4(1-) = [Re(CO)2(P(C6H5)2(OC2H5))3]B(C6H5)4 (209606-63-3)

Guidance literature:
