meso-Stilbene dibromide is an organic compound with a formula of (C 6 H 5 CH(Br)) 2. [3] It is one of three isomeric stilbene dibromides, the others being the pair of enantiomers. All are white solids. [4]
Bromination of trans-stilbene produces predominantly meso-1,2-dibromo-1,2-diphenylethane (sometimes called meso-stilbene dibromide), in line with a mechanism involving a cyclic bromonium ion intermediate of a typical electrophilic bromine addition reaction; [21] cis-stilbene yields a racemic mixture of the two enantiomers of 1,2-dibromo-1,2 ...
1,2-Dibromoethane has wider applications in the preparation of other organic compounds including those carrying modified diazocine rings [9] and vinyl bromide that is a precursor to some fire retardants. [4] In organic synthesis, 1,2-dibromoethane is used to brominate carbanions and to activate magnesium for certain Grignard reagents.
Dibromoethane can refer to either of two isomeric organobromides with the molecular formula C 2 H 4 Br 2: 1,1-Dibromoethane (ethylidene dibromide) 1,2-Dibromoethane (ethylene dibromide)
1,2-Dibromoethylene, also known as 1,2-dibromoethene and acetylene dibromide, is a dihalogenated unsaturated compound with one bromine on each of the two carbon atoms. There are two isomers of this compound, cis and trans .
1,2-Dibromotetrachloroethane (DBTCE) is an organohalide with the chemical formula C 2 Br 2 Cl 4. It is a crystalline solid that emits lachrymatory ( tear -producing) vapours. [ 2 ] Dibromotetrachloroethane can be used as a fungicide , [ 2 ] flame retardant [ 3 ] and a source for bromine in the laboratory. [ 4 ]
In one preparation for this compound, benzil is condensed with hydrazine to give the bis, which is oxidized with mercury(II) oxide. [2] Alternatively stilbene is brominated, and the resulting dibromodiphenylethane is subjected to dehydrohalogenation . [ 3 ]
