The Uses of 1,2-Dibromotetrachloroethane
1,2-dibromotetrachloroethane is used as a fire-proofing agent. It is actively involved in the conversion of sulfones to alkenes by Ramberg-Backlund rearrangement. It is an effective replacement for ozone depleting solvents like dibromodifluoromethane and tetrabromodifluoroethane. It is also utilized as a brominating reagent. In analytical chemistry, it is used in quantitative determination of perhalogenated compounds by high-performance liquid chromatography (HPLC).
General Description
1,2-Dibromotetrachloroethane acts as halogenating reagent for the one-pot conversion of sulfones to alkenes by Ramberg-B?cklund rearrangement. It is a useful brominating reagent for diaryl TeII species.
Synthesis
1,2-Dibromotetrachloroethane is prepared by reacting Tetrachloroethylene with Bromine refluxed for 2h.
