The liquid-phase chlorination of isomeric dichlorobutenes in a nonpolar medium was investigated in the presence of tert-butylpyrocatechol and without additions.The addition of tert-butylpyrocatechol leads to an increase in the yield of the products from anomalous chlorination and to a decrease in the yield of the products from normal addition.Increase in temperature during the chlorination of dichlorobutenes in the absence of tert-butylpyrocatechol promotes the formation of the normal addition products.It was suggested that the anomalous reaction, which leads to chlorides of the allyl and vinyl types, takes place by a molecular mechanism while the normal addition reaction takes place by both mechanism (molecular and radical).

The liquid-phase chlorination of 2-halogeno-2-butenes in the presence of tert-butylpyrocatechol leads to the formation of the products from an anomalous reaction (2,3-dihalogeno-1-butenes), substitution of hydrogen at the double bond (2,3-dihalogeno-2-butenes), and normal addition (2,2,3-trihalogenobutanes).The ratios of these compounds are 70:6:24 in the case of 2-chloro-2-butene and 54:7.5:38.5 in the case of 2-bromo-2-butene.During the chlorination of 2-chloro-2-butene in the presence of sodium bicarbonate the formation of 3-chloro-2-butanol (20percent) was observed as a result of the combined addition of chlorine and water.
