14dibromobut2ene

14dibromobut2ene is an organic compound with the chemical formula C4H6Br2. It is a halogenated alkene, specifically a dibromoalkene, where two bromine atoms are attached to a four-carbon chain containing a double bond. The "2ene" in the name indicates that the double bond is located between the second and third carbon atoms. The "1,4dibromo" signifies the positions of the bromine atoms on the first and fourth carbon atoms of the butane chain.

This compound can exist as geometric isomers due to the presence of the double bond. These are cis-1,4dibromobut-2-ene and trans-1,4dibromobut-2-ene. The specific isomer depends on the spatial arrangement of the substituents around the double bond. The physical properties of 1,4dibromobut-2-ene, such as melting point and boiling point, will differ between these isomers.

1,4dibromobut-2-ene is typically synthesized through reactions involving but-2-yne or butadiene. For instance, the addition of bromine to butadiene can lead to the formation of dibrominated products, and under specific conditions, 1,4dibromobut-2-ene can be obtained. It is a reactive compound due to the presence of both the double bond and the carbon-bromine bonds, making it useful as an intermediate in organic synthesis. It can undergo various reactions, including nucleophilic substitution and addition reactions across the double bond. Safety precautions should be observed when handling 1,4dibromobut-2-ene, as halogenated organic compounds can be irritants or possess other toxicological properties.
