Technology Process of η6-benzenebis(trimethylphosphine)phenylrhenium

There total 2 articles about η6-benzenebis(trimethylphosphine)phenylrhenium 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: 30.0%

rhenium + trimethylphosphane (594-09-2) → η6-benzenebis(trimethylphosphine)phenylrhenium (90885-78-2) + bis[η6-benzene-bis(trimethylphosphine)rhenium] (90885-77-1)

Guidance literature:

With benzene; In neat (no solvent); Re atoms were vapourised from a positive electron gun furnace and co-condensed with C6H6-PMe3 (5:1) mixt. over a period of 4 h at -195°C, volatiles were removed in vacuo; purified by chromy. and crystallization; identified by NMR spectra;

Reference yield: 2.0%

rhenium + ammonium tetrafluroborate (13826-83-0) + trimethylphosphane (594-09-2) → η6-benzenebis(trimethylphosphine)phenylrhenium (90885-78-2) + bis[η6-benzene-bis(trimethylphosphine)rhenium] (90885-77-1) + η6-benzenebis(trimethylphosphine)dihydridorhenium tetrafluoroborate (108070-51-5)

Guidance literature:

With benzene; In neat (no solvent, gas phase); co-condensation of Re-atoms (22 mmol) with a 5:1 molar mixt. of C6H6 and P(CH3)3 for 4 h (electron-gun furnace, 1E-4 torr); warming to room temp.; washing (toluene); filtn. and concn.; extn. with petroleum ether, filtn. and concn.; chromy. on neutral alumina column; elution with toluene, (C2H5)2O and aq. acetone, isolation of complexes from eluates; elem. anal.;
