Technology Process of dibromotriphenylbismuth

There total 13 articles about dibromotriphenylbismuth 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: 91.0%

triphenylbismuth diformate (153289-73-7) → triphenylbismuth dibromide (28719-55-3,7065-17-0)

Guidance literature:

With NaBr; In water; benzene; aq. NaBr soln. added in excess to soln. of the diformate in benzene; vigorous stirring for 10 min; sepn. of organic layer; drying (MgSO4); evapn. under reduced pressure gave crystals;

Reference yield: 79.0%

{(C6H5)4Bi}(1+)*Br3(1-)={(C6H5)4Bi}Br3 → triphenylbismuth dibromide (28719-55-3,7065-17-0)

Guidance literature:

byproducts: C6H5Br; slow heating to 5°C in 15 h;

Reference yield: 40.0%

2,6-dibromo-4-chlorophenol (5324-13-0) + triphenylbismuthane (603-33-8) → dibromotriphenylbismuth (28719-55-3,7065-17-0) + bis(2,6-dibromo-4-chlorophenoxy)triphenylbismuth (851392-40-0)

Guidance literature:

With H₂O₂; In diethyl ether; water; byproducts: H2O; 2,6-dibromo-4-chlorophenol and 31% aq. soln. of H2O2 in Et2O were added to soln. of Ph3Bi in Et2O (molar ratio Ph3Bi, Br2ClC6H2OH, H2O2 was 1:2:1); kept at 20°C for 24 h; solvent removed; residue extd. (hexane); extd. vol. was reduced; soln. cooled to -18°C; crystals of Ph3Bi(OC6H2Br2Cl) were dried; residueextd. (toluene); toluene evapd.; Ph3BiBr was obtained;
