Technology Process of Tetraethyldistibine

There total 4 articles about Tetraethyldistibine 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: 95.2%

tetraethyldistibine + ethylene dibromide (106-93-4) → ethene (74-85-1) + tetraethyldistibine (4669-92-5)

Guidance literature:

In tetrahydrofuran; at -25°C, hydrolysis with concd. aq. NH4Cl soln., drying of organic layer, vac. distn.;

Reference yield: 60.0%

tetraethyldistibine + chloro-bis(dimethylamino)borane (6562-41-0) → tris(dimethylamino)borane (4375-83-1) + bis(dimethylamino)diethylstibinoborane (37493-74-6) + tetraethyldistibine (4669-92-5)

Guidance literature:

In diethyl ether; byproducts: LiCl; at -10°C in N2 atm., stirring for 16 h in the absence of light, filtering, evapn. in high vac. at 0°C;

Reference yield:

antimony (7440-36-0) + ethyl radical (2025-56-1) → triethylantimony (617-85-6) + tetraethyldistibine (4669-92-5)

Guidance literature:

With hydrogen; reacting of C2H5 radicals under reduced pressure in H2 stream with heated Sb mirror; fractional condensation;
