There total 2 articles about tetrakis(triphenylarsine)gold(I) tetrafluoroborate 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: 95.0%

silver tetrafluoroborate (14104-20-2) + (triphenylarsine)gold(I) chloride (25749-29-5) + triphenyl-arsane (603-32-7) → tetrakis(triphenylarsine)gold(I) tetrafluoroborate (197778-27-1)

Guidance literature:

In tetrahydrofuran; dichloromethane; byproducts: AgCl; (N2); addn. of AgBF4 in THF with stirring to the Au complex in CH2Cl2, stirring (room temp., 15 min), addn. of AsPh3 in CH2Cl2, stirring (room temp., 3 h); filtration, removal of volatiles (0.8 Torr, 25°C), crystn. by layering Et2O onto a CH2Cl2 soln.; elem. anal.;

Reference yield: 40.3%

sodium tetrafluoroborate (13755-29-8) + (triphenylarsine)gold(I) chloride (25749-29-5) + silver(l) oxide (20667-12-3) → tetrakis(triphenylarsine)gold(I) tetrafluoroborate (197778-27-1) + Au(As(C6H5)3)2(1+)*BF4(1-) = [Au(As(C6H5)3)2]BF4 (204771-53-9) + O(Au(As(C6H5)3))3(1+)*BF4(1-) = [O(Au(As(C6H5)3))3]BF4 (204771-55-1)

Guidance literature:

In tetrahydrofuran; (N2); stirring (room temp. 3 h); removal of volatiles (vac., room temp.), extn. (benzene; CH2Cl2), concn.(vac.), layering with Et2O, crystn. within 2 d, manual sepn. of crystal s; elem. anal.;
