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.
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.

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 ]
[3] [4] Its chemical name is dimethyl 1,2-dibromo-2,2-dichloroethylphosphate. Naled is stable in anhydrous condition and must be stored away from light. It must also be stored under normal pressure and temperatures. It degrades in the presence of water and alkali, and produces toxic chloride fumes if exposed to acids or acidic fumes.
1,2-Dibromo-3-chloropropane (dibromochloropropane), better known as DBCP, is the organic compound with the formula BrCH(CH 2 Br)(CH 2 Cl). It is a dense colorless liquid although commercial samples often appear amber or even brown. It is the active ingredient in the nematicide Nemagon, also known as Fumazone.
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)
