Technology Process of Trimethylphosphine selenide

There total 8 articles about Trimethylphosphine selenide 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: 88.0%

bis(1,5-cyclooctanediylboryl)diselenide (120789-32-4) + trimethylphosphane (594-09-2) → trimethylphosphane selenide (20819-54-9) + (PB) trimethylphosphanebis(1,5-cyclooctanediylboryl)monoselenide (120771-74-6)

Guidance literature:

In toluene; a soln. of trimethylphosphane is dropped to a suspension of (C8H14B)2Se2 in toluene, stirring at room temp. for 2 h, removing of the solvent, sublimation of SePMe3 at 60-80°C/0.001 Torr and of (C8H14B)2Se(PMe3) at 110-120°C/0.001 Torr;

Reference yield: 85.0%

selenium + tetrakis(trimethylphosphine)cobalt(0) (33152-37-3) → di-μ-selenidobis{tris(trimethylphosphine)cobalt} + trimethylphosphane selenide (20819-54-9)

Guidance literature:

In diethyl ether; Ar atmosphere, stirring (20°C, 15 h), removing of solvent (vac.), extraction with pentane (fritted disc); crystn. on cooling (dry ice); elem. anal.;

Reference yield: 77.0%

di-μ-selenidobis{tris(trimethylphosphine)cobalt} → trimethylphosphane selenide (20819-54-9)

Guidance literature:
