Technology Process of W₂Br₆(P(CH₃)2C₆H₅)3

There total 2 articles about W₂Br₆(P(CH₃)2C₆H₅)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: 35.0%

tungsten(V) bromide (13470-11-6) + Dimethyl(phenyl)phosphine (672-66-2) → W2Br6(P(CH3)2C6H5)3 (139376-29-7) + WOBr2(P(CH3)2C6H5)3*0.5C7H8

Guidance literature:

With Na/Hg; In toluene; under Ar, addn. of Na/Hg to WBr5 in toluene, stirred for 30 min, addn. of phosphine, stirred for 2 d; filtered under Ar, dissolved in methanol, kept in the refrigerator for 3 d: WOBr2(PMe2Ph)3*0.7C7H8, soln. layered with hexane, isolated after 3 weeks;

Reference yield:

tungsten(V) bromide (13470-11-6) + sodium triethylborohydride + Dimethyl(phenyl)phosphine (672-66-2) → W2Br6(P(CH3)2C6H5)3 (139376-29-7)

Guidance literature:

In tetrahydrofuran; toluene; under Ar, addn. of B-compd. in THF to WBr5 in toluene, stirred for 30 min, addn. of phosphine, stirred for 2 d, careful elimination of oxygen; filtered under Ar, soln. layered with hexane, isolated after 3 weeks;

upstream raw materials:

tungsten(V) bromide

Dimethyl(phenyl)phosphine
