There total 1 articles about Dicarbonyl(η5-cyclopentadienyl)(η2-ethylen)(triphenylphosphan)wolfram-tetrafluoroborat 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: 55.0%

oxirane (75-21-8,99932-75-9) + tetrafluoroboric acid diethyl ether (67969-82-8) + CpW(CO)2(PPh3)Cl → Dicarbonyl(η5-cyclopentadienyl)(η2-ethylen)(triphenylphosphan)wolfram-tetrafluoroborat (78100-42-2)

Guidance literature:

With sodium amalgam; In tetrahydrofuran; under N2 WCl-compd. reducted with NaHg in THF, ethylene oxide added to this soln. at -55°C, mixt. stirred for 24 at room temp., cooled to -40°C and HBF4*Et2O added two times; crystals washed with Et2O and pentane, dissolved in acetone, soln. filtered, pentane added to filtrate, complex washed with pentane, dried in vac.; elem. anal.;

Reference yield: 39.0%

1,3-diferrocenyl-1,3-propanedione (12320-80-8) + Dicarbonyl(η5-cyclopentadienyl)(η2-ethylen)(triphenylphosphan)wolfram-tetrafluoroborat (78100-42-2) → [FcC(O)]2CH(η1-CH2CH2)W(CO)2CpPPh3
