Useful:

• Canonical SMILES: [Ga+3].[Br-].[Br-].[Br-]
• Uses: Gallium(III) bromide is used as organic intermediates. It is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. Gallium(III) bromide may be used to catalyze the coupling of indoles with phenylacetylene to form 1,1-bis(1H-3-indolyl)-1-phenylethanes.

Technology Process of Gallium;tribromide

There total 10 articles about Gallium;tribromide 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: 84.0%

gallium (7440-55-3) + bromine (7726-95-6) → gallium(III) bromide (13450-88-9)

Guidance literature:

In further solvent(s); N2-atmosphere; excess Br2, stirring in perfluorodecalin for 1 h; collection (filtration), drying (vac.); elem. anal.;

Reference yield:

cadmium(II) selenide + gallium selenide bromide → Cd2GaSe3Br + gallium(III) bromide (13450-88-9)

Guidance literature:

In neat (no solvent, solid phase); mixt. of the starting materials heated in evacuated sealed quartz tubes to 500-900°C; decompn. of educts ocurrs, GaBr3 sublimates off;

Reference yield:

cadmium telluride + GaTeBr → Cd2GaTe3Br + gallium(III) bromide (13450-88-9)

Guidance literature:

In neat (no solvent, solid phase); mixt. of the starting materials heated in evacuated sealed quartz tubes to 500-900°C; decompn. of educts ocurrs, GaBr3 sublimates off;
