2,3,3,4,4-Pentachlorobutyric acid was obtained with a preparative yield by the reaction of 1,1,1,2,3,3,4,4-octachlorobutane with oleum.The dehydrochlorination of octachlorobutane with an equimolar amount of an aqueous solution of sodium hydroxide, catalyzed by triethylbenzylammonium chloride, takes place by the elimination of one molecule of hydrogen chloride from positions 1,2 and 2,3 with the formation of isomeric heptachlorobutenes.Hydrolysis of the latter with fuming nitric acid gave the difficultly obtainable 1,1,2,4,4-pentachloro-1-buten-3-one and Z-α,β,χ,χ-tetrachlorocrotonic acid.
