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 .
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 ]
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)
