Technology Process of rhenium tetrabromide oxide

There total 3 articles about rhenium tetrabromide oxide 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: 100.0%

ammonium perrhenate + sodium bromide (7647-15-6) → rhenium(VI) tetrabromide oxide (23601-08-3)

Guidance literature:

In sulfuric acid; NaBr addn. to NH4ReO4 soln. in concd. H2SO4 (crystn.); extn. (toluene), distn. off of toluene; elem. anal.;

Reference yield: 88.0%

carbonyl dibromide (593-95-3) + rhenium(VII) oxide → rhenium(VI) tetrabromide oxide (23601-08-3)

Guidance literature:

In neat (no solvent); byproducts: CO2, Br2; condensing COBr2 onto Re2O7, heating (sealed tube, 125°C, 10 d); cooling the tube to -95°C, removal of volatiles (vac.); elem. anal.;

Reference yield:

per-rhenic acid (207984-93-8) + sodium bromide (7647-15-6) → rhenium(VI) tetrabromide oxide (23601-08-3)

Guidance literature:

In sulfuric acid; byproducts: HBr, Br2; dissoln. of HReO4 in 98% H2SO4, dropwise addn. of 20-50 fold excess NaBr, stirring (20-30 min); other alkali metal bromides can be used instead of NaBr; extn. (toluene), distn. off of solvent (vac., room temp.);
