Both normal addition products (tetrahalogenobutanes) and anomalous reaction products (2,3,3-trihalogeno-1-butenes) are formed during the liquid-phase chlorination of 2,3-dihalogeno-2-butenes (2,3-dichloro-, 2-chloro-3-bromo-, and 2,3-dibromo-2-butenes) in the presence of an inhibitor of radical reactions.Below 20 deg C the cis isomers are chlorinated more rapidly than the trans isomers, mainly forming the anomalous reaction products.During chlorination above 20 deg C (20-40 deg C) the process is complicated by the partial isomerization of the 2,3,3-trihalogeno-1-butene which forms into 1,2,3-trihalogeno-2-butene and, in the case of the bromine-substituted butenes, by substitution of the bromine atom by chloring.
