2klorobuta13dieeni

2-Chlorobuta-1,3-diene is a halogenated diene with the chemical formula C4H5Cl. It is a colorless liquid at room temperature. Its structure consists of a four-carbon chain with two double bonds at positions 1 and 3, and a chlorine atom attached to the second carbon. The arrangement of these double bonds makes it a conjugated diene.

This compound can be synthesized through various chemical reactions, often involving the dehydrochlorination of chlorinated butanes or related precursors. It is known to be a reactive molecule due to the presence of both the diene system and the chlorine atom.

2-Chlorobuta-1,3-diene is primarily used as a monomer in the synthesis of polymers. Its ability to undergo polymerization, particularly through free-radical or anionic mechanisms, allows for the creation of specialized rubbery materials. These polymers can exhibit properties influenced by the presence of the chlorine atom, potentially affecting their chemical resistance, flammability, and mechanical characteristics. It can also be used as an intermediate in the synthesis of other organic compounds. Due to its reactivity, proper handling and storage procedures are necessary.
