13Dichlorobut2ene

1,3-Dichlorobut-2-ene is an organic compound with the chemical formula C4H6Cl2. It is a chlorinated derivative of butadiene, a common monomer used in the production of synthetic rubber. The molecule consists of a butadiene backbone with two chlorine atoms substituted at the 1 and 3 positions. The double bond is located between the second and third carbon atoms.

1,3-Dichlorobut-2-ene is typically prepared through the chlorination of butadiene using chlorine gas or a chlorinating agent. The reaction is usually carried out in the presence of a catalyst to control the selectivity and prevent over-chlorination. The resulting product is a mixture of cis and trans isomers, with the trans isomer being the more stable.

This compound is used as a precursor in the synthesis of various chlorinated polymers and as a building block in organic synthesis. It is also used in the production of certain pesticides and herbicides. However, due to its potential health and environmental hazards, the use of 1,3-Dichlorobut-2-ene is regulated in many countries.

The toxicity of 1,3-Dichlorobut-2-ene is primarily due to its ability to disrupt the electron transport chain in mitochondria, leading to cellular damage and death. It is also a potent irritant to the skin, eyes, and respiratory system. Proper handling and disposal procedures should be followed when working with this compound to minimize potential health and environmental risks.
