Technology Process of Thiophosphoryl bromide

There total 25 articles about Thiophosphoryl bromide 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:

hydrogen sulfide (7783-06-4) + phosphorus pentabromide (7789-69-7) → thiophosphoryl(V) bromide (3931-89-3) + hydrogen bromide (10035-10-6,12258-64-9)

Guidance literature:

In neat (no solvent); react. of gaseous H2S with PBr5 at ambient temp.; evolution of heat;;

Reference yield:

phosphorus sulfide (1314-85-8) + bromocyane (506-68-3) → thiophosphoryl(V) bromide (3931-89-3) + cyanide(1-) (57-12-5) + phosphorus tribromide (7789-60-8)

Guidance literature:

With aluminium trichloride; at the m.p. of BrCN;

Reference yield:

antimony(III) sulfide + phosphorus pentabromide (7789-69-7) → thiophosphoryl(V) bromide (3931-89-3) + antimony(III) bromide (7789-61-9)
