2,3-Dichlorobutadiene

2,3-Dichlorobutadiene is the organic compound with the formula H2C=C(Cl)C(Cl)=CH2. This colorless liquid is prone to polymerization, moreso than 2-chlorobutadiene (chloroprene). It is used to produce specialized neoprene rubbers. It can be prepared by the copper-catalyzed isomerization of dichlorobutynes. Alternatively dehydrochlorination of 2,3,4-trichloro-1-butene: CH2=C(Cl)CH(Cl)CH2Cl + NaOH → CH2=C(Cl)C(Cl)=CH2 + NaCl + H2O 2,3-Dichlorobutadiene is a precursor to 2,3-diarylbutadienes.
