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)
The preparation of EtBr stands as a model for the synthesis of bromoalkanes in general. It is usually prepared by the addition of hydrogen bromide to ethene: . H 2 C=CH 2 + HBr → H 3 C-CH 2 Br
1,1-Dibromoethane is a clear, slightly brown, flammable chemical compound. [3] It is classified as the organobromine compound, and has the chemical formula C 2 H 4 Br 2 [4] and it is a position isomer of 1,2-dibromoethane. It is commonly seen in industrial chemistry, where it is used as a fuel additive. [5]
Grignard reagents or Grignard compounds are chemical compounds with the general formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH 3 and phenylmagnesium bromide (C 6 H 5 )−Mg−Br .
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
The molecular formula C 2 H 4 Br 2 (molar mass: 187.86 g/mol, exact mass: 185.8680 u) may refer to: 1,1-Dibromoethane (ethylidene dibromide) 1,2-Dibromoethane , or ethylene dibromide (EDB)
1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
